What used to be a flourishing indie game inspired from some of gaming's best retro is now a shell of it's former self. Spiral Knights was fun when it was under indie ownership and it was still great when Nick was leading the development team. He left with a somber note and now I see why; the developer is clearly more interested in adding grind walls to get money out of it's players than it is providing a fun and balanced gameplay. RIP Spiral Knights, SEGA ruins yet another good thing.

Good night sweet prince.


Spiral Knights started out as an indie game developed and funded by Three Rings (simply called OOO from here on). It got many rewards and was lauded by critics cause of it's fun and unique playstyle for an MMO and easy to learn, hard to master approach. Like many games it has dual economy; in game money being >crowns< and the real world alternative >crystal energy<.

For a short while, one could easy get energy crystals from simply playing the game to earn crowns which they could then trade for EC. This worked for a while and it was very fair way for players to get the premium gear and goodies the game had to offer without ever needing to spending actual cash. The game did, however, limit how much you could play in a single day with MIST ENERGY, which you used to progress down floors into game's dungeons. You could get about an hour or so of play time of your 100 daily mist energy, so it was good incentive to buy an elevator pass so you could play the game as much as you wanted. For small price of $5.95, you could play the game for as much as you wanted for as long as you wanted (see how I racked up 2000+ hours?).

The game always had balance issues but with enough practice, you could overcome them. Swordsmen had the best selection of armor and weapons, dished out the most damage and had the most of the game's content dedicated to it. Gunners were gimped by poor damage output, a 3 bullet clip, and reduced movement speed when firing. Bomber probably had the worst of it all. Bombs take what feels like an eternity to charge, and you can only place down one bomb at a time. The blast radius was embracing unless you had a 4* or 5* weapon and even then, you were at large risk of dying because of how bombs functioned.

Did I mention they teased opening the Core for years?

Things started to turn sour, though, once SEGA purchased the developer. Content started to slow to a halt, and a steady increase in cosmetic promotions were now the common flavor of the month. SEGA, of course was more interested in milking the game's acclaim for cash rather than developing upon it's success as a wonderful, retro gaming-inspired masterpiece. It took almost a year for the guild hall update to finally release and it took even longer for Gunner Update to hit the players. In between that, there was dozens of promotional boxes featuring nothing but armor and weapon recolors and underwhelming chances of getting said items. It was a skinner box idea to start with that only got worse, as at this point in the game, the promo boxes didn't even provide the player with EC.

There were two nails in the coffin for this game: the first being the addition of the Furnace and the departure of head developer/game creative director Nick Popovich. This game was a love letter of gaming for Nick and it really showed. Sadly, he left on a subtly sad note and moved on with his life.

It was clear at that point that SEGA was simply using the game was means of collecting easy cash off of young people with no knowledge of how their gambling--erm--lockboxes work. rather than make an evolving game. OOO is now a money machine for SEGA and nothing else. The Furnace turned the game into an nigh painful grindfest and it's god awful at it too. "Heat" up your gear now and spend rare fire crystals at a chance at leveling up your gear.

Do yourself a favor, if you see this game in your recommended feed by Steam, click "Not Interested" and said yourself the wasted harddrive space.

.... oh, the core finally opened up. Big whoop.

I suppose it might be time for me to write this review, considering I've played since shortly after it became available on Steam. Granted, I've taken some pretty lengthy breaks, but I've logged quite a few hours into this game.

TL;DR: A personally nostalgiac MMO that isn't quite what it used to be.

When I started playing this game, I pretty much played solo. There were no missions, nor was the story something you had to experience along the way - back then, all it took was learning the mechanics and diving into it. It was pretty grindy back then, but definitely manageable. As a new player, and with content being released a little more regularly then, grinding consistently paid off. If that were still the case, I'd probably recommend this game.

I got about halfway through levelling up my first set of gear when I realized how quickly things would go if I were in a guild. My first guild experience lasted a day, and I hopped through a few smaller ones until I found my first home. I'm glad to say that a few people from that guild I'm still friends with in real life - and honestly, there are only a handful of MMOs that have actually brought people into my life for an extended period of time outside of game. I suppose that adds to the nostalgia. I got a little more levelled up in that guild, but my interest started to fade and I stopped playing.

When I started again, I hopped around a few more times, settling in for a month or two with some relatively active guilds, but didn't find another in-game group that I clicked with until I joined my current guild. Again, I still keep in contact with several guild mates to this day, not as often lately but it's nice knowing they're there and that they helped me through a time in my life that was a bit troubled. I reached end game with them, and started to feel the interest fade, as well. The mission system took some of the mystery out of the game, but that wasn't too bad. Then energy was replaced with crystals, and the game essentially became pay-to-win. A lot of people stopped playing.

The community in this game has always been one of its strong suits, something that would be a definitive selling point so long as it thrived. However, I don't really see it thriving like it used to. Sure, I have friends that play still, and there are many other great people online pretty regularly. I could go on and on with examples about how changes have impacted the community, though - when I started playing, random clusters of players just chatting away was a regular sight in the more common areas. I don't see that as much now. A lot of community talk has gone from focusing on lore or gameplay elements to constant wondering when something new will happen with the game.

Overall, I concur with what many other reviews say. The Zelda-esque gameplay is really appealing, and the art, both audio and visual, is unforgettable. Yet it has lost its charm. For new players, getting to end-game would take a lot of time or money, or both, and even then, what good does it do? While the journey to the end itself is quite fun, and there is an opportunity to meet some great people along the way, there isn't much to expect after. Even as a completionist, I've pretty much given up on levelling all of my gear - it just doesn't seem worth it, and at this point, things are too repetitive.

Do I recommend this game? A few years ago, sure, but now, I sadly cannot. If that changes, I'll be sure to update my review, but I'm not counting on it.

Used to be a good game, but you get to a point where you NEED to pay to win (tier 4 stuff). At that point it is immposible to progress without spending a dollar. I understand that the devs need money to run the game (I have bought the $7 DLC by the way), but this would be a far better game if it was a flat fee of $10 to buy the game, with no grinding and overpriced stuff. (Shadowkeys, energy)

So... i've completley lost my faith in this game.

It was quite fun when I got it, and still great 900 hours later. Not many free games have the very positive reviews this one does, and guess what?
OOO eliminated the mist energy system. Players can now play unlimited levels!
There's PvP, PvE, and a pretty decent chat system. Players can play with their friends or with random people, or even alone.
Even with the mist system I would still recommend it, and without that limitation I definitely suggest that people play this. It doesn't have very heavy graphics requirements and can run well on dinosaur computers on low.
The developers are updating, slowly but surely.

Kinda decent f2p mmorpg that has no class limitations(hooray!)(and that game where i drained too much hours...)

Community: In PvE, you may encounter friendly ppl(i managed to even encounter person that i love :o), while in PvP mostly complainers(those who complain about AT&T releasing too much of 1st in battle xD) or persons that make you turn into complainer.(As always!)

Main review part:
Graphics: Everything looks kinda pretty, but performance is not what expected for java and openGL...(8/10)
Gameplay: SK features huge choice of equipment, which adds variety to the gear and gameplay itself(like you can use guns, or bombs, or swords.. or 2 of those... or all 3 xD) But because this game features grinding in big quantities you
may get bored(or may not if you do co-op with your friend(s))(10/10)
Controls: In order to rekt m8s you need to change much(like binding weps to keys)(8/10)
Setting: Kinda variable even if its supposed to be under ground.(10/10)
Story: It's kinda interesting but begins to be rly interesting only when OOO decides to release new missions xD(like those new levels featuring herex 'n stuff)(8/10)
Late game playability: This game features much equipment/accessories/stuff that will make you grind it to get it. Also getting last prestige badge which can take up to 5 months.(10/10)

Overall rating: This game can be very good if you have friends and you're patient, but if not then it's not for ya... anyway this game doesn't cost a penny, so better try it out!
Rank: S (9,0/10)
