Well, it's not as good as the Arcade Stages, but it is better then the PS2 version. Which is kind of saying something.

Well, if you've played either the Arcade Stage or the PS2 version, you're bound to fall in love with this. It's an instant classic for the PSP and never gets old. There is plenty of extras to keep anyone busy for countless hours. The handling in the game takes awhile to get used to, but after awhile it is so smooth nothing could feel more right. Same thing with the Arcade Stage and the PS2 Version, if it's in the manga or anime, it's in the game. ID:SS also added a few more mountain passes for your racing pleasure. The only downside to this game is that instead of winning specific parts by reaching certain amounts of CP like in the other versions, in this one at the end of every race you have to pick one out of four cards. That one card you pick could be specific part upgrade or something useless. I find it to be rather annoying when you can't seem to get what you need. Especially when you need it the most.

Overall a great game. My favorite PSP game by far. Check it out.
