Fun and the cutscenes are lol. No widescreen is lame but 4:3 is fine for this game I guess. The BetterSADX mod adds widescreen but makes menus small at higher resolutions, so going modless has at least the advantage of normal size menus. It also seems like running the game at high resolutions (mod or not) makes the sky chase missions way harder to lock onto stuff since the reticle gets really small.

I have played this countless times on my Gamecube and still have it but I got this one in a HumblBundle package because why not?

The game runs smoothly for me and the keyboard controls are fine
However the game runs faster then the Gamecube version, I noticed this in Chao's 2nd battle against Sonic where his attacks moved much faster then they should of.

So far I have found nothing wrong with the game, everything is working how it should be and I am enjoying my childhood on my PC, hearing that NiGHTS music just makes me smile.
If you don't have the original game anymore then maybe pick this one up, I do enjoy this one out of them because of the HUD world and Tails spin-attack. And than Big ruins it >_>

Purchased the game for nostalgia's sake, which I imagine is the reason several others easily forked over money (perhaps not retail price given than it's something like 9 bucks but a lot less if you are wise enough to get it on sale or in a bundle).

Obviously, this isn't the best Sonic adventure game (Adventure 2 objectively is, as far as I'm concerned) but it outranks some of the later games (if only by enjoyability).

The better options of the games include Bigs' arc and the Chao feature (which, I'm sure is everyone's favourite part because who doesn't like nursing a tiny creature into becoming a devil, an angel or something else?!?!??!?)

Oh, this one has aged very badly. Really twitchy controls, a terrible camera and graphics that have not stood the test of time.

It's quite fun if you know what you're doing. However the game is quite buggy and therefore rage-inducing.
Sonic's levels are fun and fast paced (except for the last one) as that's Sonic's theme, fast.
Tails is straight OP being able to destroy most of the levels with his flight which make them hilarious. Just imagine Sonic's face as he watches Tails jump off of the edge only to hit the animal capsule 28 seconds later.
Knuckles' mechanics and story were fun, but not his actual levels. Searching for the Master Emerald pieces was boring, they didn't even bother to change it in Sonic Adventure 2.
Amy's levels were the most painful to me, seeing as how slow she is. By the time you've built up enough speed to Hammer-Jump, you have to turn a corner and then speed up again. Although the final stage was fun.
Gamma's levels were really fun but it was tragic from beginning to end despite having a happy ending. Gamma's story was sad until he was destroyed, basically. The sweet release of death.
Big...Wasn't as painful as people make it out to be. Although they were VERY slow and boring that doesn't make it difficult.

Overall it's quite fun but it's a pain having to do 6 different stories which involve you replaying the same levels and getting all the emblems is tedious and not worth it.
I'd give this game a 6/10

Disclaimer: this wasn't part of my childhood, believe it or not. I played the demo years back, and that's it.

To be frank, I'm quite mixed on this one. It definitely shows its age.

Some good graphics for the early 2000's, but draw distance issues, even with the BetterSADX mod, hurts it. It was lauded back when 3D and open world was new, but not today. Character mouth flaps are uncanny, and they're anthro cartoon animals for crying out loud.

I'll give credit where it's due, the music is good for the most part. "Open your Heart" in particular rocks. The rest of the sound effects are quite lacking. Voice acting is grating and often annoying, and doesn't take into account other sound effects. "Get a load of this" anyone?

Gameplay is divided into 6 characters with gimmicks: Sonic is straight forward, "get to the goal fast", Tails is "get to the goal before the other loser, and fast", Knuckles is "get the three emerald shards, and fast", Amy is "run away from the big robot fast", Omega is "shoot up these losers fast", and Big is... "catch a frog, fast".

I hate Big.

The camera is ♥♥♥♥. It often gets stuck in walls and otherwise doesn't let you see where you're going. Controls are camera-relative and quite sensitive, leading to a slightly annoying bump in speedier sections and bouncing off walls or otherwise losing momentum. The hub worlds could really benefit from some form of map, hints in the environment about the path to take, and objectives. The biggest danger I've encountered in the Action stages weren't the enemies, but the cheap platforming and knockback from taking damage that throws me into a bottomless pit. This feels like the start of the polygon ceiling that's plagued the Sonic series for years, and still may linger.

The game is still playable with the keyboard, but it definitely seems to be designed for gamepads.

I hate Big.

And there's bugs. I didn't find them quite as charming as many others do.

It's fairly cheap still, but if you're not some diehard Sonic fan looking to complete your collection I advise you grab it on a sale. There's some genuinely good ideas here, if you look past the other issues.

I hate Big.

One of my alltime favorite games.

The music, art style and story of this game are so charming

- Story is lovely
- HUB world is great, I love hub worlds
- Music is awesome and fits the game perfect
- Gameplay is great, although it can feel somewhat buggy and glitchy on certain stages (especially while playing sonic)
- You can play Tails outside of his vehicles (unlike in SA2 :/)

- Like I said, the gameplay using Sonic can be a bit annoying / buggy on certain stages
- The levels / minigames Sky Chase / Sky Chase 2 are hard to play using the Keyboard

Sonic Adventure for Dreamcast was probably the first game where I was old enough to actually look forward to and get excited about its upcoming release. Unfortunately I couldn't afford to buy it or a Dreamcast, but decades later I can actually play the game properly without that weird cracked PC copy that looped the twinkle park theme for every level. I still vividly remember the excited feelings of inspiration from reading about the "open" world, and story told from 6 different playable perspectives. Even though the game is actually a confusing, glitchy mess, I still feel excited for everything it aspired to be. I still look for other companies to accomplish the game that SA aspired to be, but I keep coming back to SA.

I know that a review based on emotion and nostalgia doesn't help anyone else who's considering buying it, but Sonic Adventure is my jam.

Many people reivewed this game talking about how this was a childhood favorite of theirs. My childhood, however, was largely a PS2-involved one, and any sonic games I did play were either the old 2D ones on the Mega Collection, or the ones on my older brother's old Genesis. Now years later (and after playing duds like Sonic and the Secret Rings) I finally get to play the game that forever changed Sonic the Hedgehog as we know him. After playing Sonic Adventure DX, I'm pleased to say that it is quite an enjoyable game, however, it definately shows its age in some spots.

The gameplay is interesting because each of the six main characters (Sonic, Tails, Knuckles, Amy, Big, and Gamma) have their own campaign that once unlocked can be completed at the player's own pace. Having trouble finding emeralds as Knuckles? Play with Sonic for a bit and come back to the echidna later. Not feeling up for Big fishing? Go shoot things with Gamma and deal with him later.

Sonic, Tails, and Amy relatively have the same mission structure, and that is to run to the end of the stage quickly, only while sonic's stages follow that description to a T, Tails is more about racing a computer opponent through the level to prove he's faster, and Amy, armed with a hammer, is much slower, more focused on traditional platforming, and must also avoid an indestructible robot persuer. These stages are the traditional fare for the game, and are possibly my favorite stage types for the game (especially Sonic's levels.) Sonic's first few stages might have a type of "go straight to win" feeling to them, with Emerald Coast possibly being one of the easiest to glitch levels (at least without trying), but if you give the game more of a chance beyond the first two action stagees then you will find that there's some pretty neat platforming and speed in Sonic Adventure.

Knuckles, Gamma, and Big, are the most divergent of the game's campaigns. Knuckles' campaign involves finding three emerald shards to clear the stage. I'm not really too interested in these segments, but they're relatively interesting enough to keep a sense of variety in the game. Gamma the robot is mainly a shooting game. Defecting from Eggman, you go though Sonic's stages as your mission is to shoot down all the robots to free your fellow enslaved animals and keep up your timer, with a boss battle usually at the end of a stage. Out of all the gimmicky stages, I enjoyed Gamma's the most, as they provide a unique spin on the standard stages, and manage to retain the speed-oriented spirit of sonic. Big the Cat's much-groaned-over stages involve.... Fishing for some frog. These stages feel very odd and tacked on; the game definately could have lived without these levels, but don't worry; Big's campaign is the shortest. You can spread his levels out with the other characters.

What connects the action levels together is the field stage. You have three feilds to explore and each one is big and adds a nice exploration element to the game, something I wish the more streamlined later games would have kept. There's also lots of items for each character to collect to enhance their skills for more exploration, provding a nice sense of progression. Some may complain that it is easy to get lost, but as long as you refer to the glowing orb of light located in any area then you should be able to figure it out on your own.

Before the 3D Sonic titles became known for their needlessly convoluted plotlines involving ancient prophecies and edgy rivals, Sonic Adventure 1 suprisingly stays relatively grounded under the surface and feels like the typical Sonic plot you'd expect. Eggman's trying to rule the world with the chaos emeralds again, only this time he's awakened the ancient diety Chaos, and is feeding it the emeralds to power it up. The game follows Sonic and the other protagonists on their various journeys to either stop Eggman or go on their own personal adventure. Each character has their own story arc that's simple enough to follow and doesn't get too melodramatic. The graphics and voice acting, however, give things a very campy feel, but if you enjoyed games such as the original Resident Evil for their good gameplay with cheesy, terrible voice acting, then you should find yourself enjoying SADX as much as you're laughing at how silly it gets. This game's story is not going to win any awards, but it at least doesn't try too hard to be something greater than it really is.

The music is very memorable and has plenty of great stage themes. The character themes with lyrics, however, are typical 90's SEGA cheese. You'll either hate them or find them to be a guilty pleasure. The level songs, however, feel very much like old school sonic tracks (some of them are even recycled from older games!), and fit nicely with the levels they're in.

The graphics are possibly my biggest complaint for this game. The game's visuals do not do it justice and have aged pretty badly. It gives the game a sort of unfinished feel and makes it seem almost like a joke at some points. Don't even get me started on the facial expressions of the characters. they're just hilarious. I feel the game's graphics and bugs are possibly what is most likely to detract people from this game the most, and what could cause people to prefer SA2 over SA1 (or older Sonic games over SA1&2 in general) Also for some reason this port doesn't come in widescreen. You always have this border around the screen at all times, which is quite annoying since SA2's pc port doesn't do this.

I found Sonic Adventure to be very true to the spirit of the Sonic franchise. It plays very different from what you'd expect from a Sonic game (especially if you're used to the 2D games), but like Mario 64, playing signifficantly different from your 2D games actually works in its benefit, since SADX adapted for the 3D gaming environment, and while it isn't perfect, it managed to be an enjoyable game while staying true to the Sonic feel that also provides a variety of gameplay modes to keep things interesting. I almost wish sega tried improving upon the model laid by Sonic Adventure 1 and polished it to make more neat exploration/action hybrid Sonic titles. Heck, they don't need to have multiple characters; having a game where sonic himself explores fields for items and goes into action stages would be fine by me!

So basically, you'll like Sonic Adventure if:
-You like 3D platformers like Mario 64
-You like games with an exploration aspect
-You like games with cheesy voice acting
-You want games with multiple characters with different abilities and story paths that you can tackle at your own leisure
-You're open to try a Sonic game that tries to do something different.
-You're willing to give the game time and not judge the game based on its wonky first action stage
-You're willing to tolerate a few (thankfully short) fishing minigames.

You probably won't like Sonic Adventure if:
-You aren't really that much into platformers
-If you can't really stand a game that looks really funky graphic-wise
-If a few weird glitches deter you from enjoying the game
-You're looking for an amazing storyline

Overall I'd totally recommend this game!

This game is very nostalgic in many ways for me. I can still remember when I played this game for the first time and I loved everything about it. It may not be good to today's standards, but at it's time, it was one of a kind!
