The original AudioSurf was the first Steam game I ever owned. At the time I didn't know about the store, or even that there were other games. All I knew was that there was this cool little game that turned my songs into racetracks and it was awesome. Now obviously I eventually stumbled onto the rest of Steam from there. And it was while using Steam one day I saw that the game had a sequel.
Now personally I am of the belief that AudioSurf never needed a sequel. It was a game with endless replayability. A new song comes out? Play it. What would a sequel do that the original hadn't already done better?
I decided to find out. I put the game on for 70 minutes approximately a year ago after it came out. It was ugly, no clean interface, and worst of all you were forced into the new wakeboarding mode. I put it aside, thinking it would get better. Fast forward a year later to tonight when i see the latest update and decide to see if it's any better. Thirty minutes later, I can determine that it has gotten better, but not by much.
The catchy title screen and the mellow background tune as you chose your mode and track? Gone. In it's place is just a static menu with no real background noise.
Remember the lovely roller coaster of a track with all sort of shapes and patterns exploding around you? Yeah well that's been replaced by a bobsled chute with some fancy colors.
The crisp and cool looking racers and blocks? The racers all look generic and you're collecting blobs of jelly rather then blocks.
The wakeboarding mode is alright but I just want to race, not remember to hit jumps and then scramble to remember how to do the tricks. There's also a new mode called AudioSprint where you hit two buttons to duck or slide under blocks. It's different but with a fast paced song it becomes a chore and a frustration rather then anything fun.
This game can be modded....yay? I don't see the appeal of it myself.
So basically TL:DR, the game doesn't do enough to make itself stand out from the original. The core gameplay is there, but altered and made to look like crap compared to the original. The new modes are only okay, nothing exceptional, and you can mod the game if that's something that should appeal to you in any way, shape, or form.
Reccomendation: Just go buy the orignal.
