Well, I said I’d give you my thoughts on it and so here we go.

I played 2 solid hours of PSP Ridge Racer (undoubtedly excellent graphics) prior to playing Rayman so I was in the mood for a bit of an adventure…boy did I get it!
Rayman is an entertaining adventure exploration game that will keep most people entertained for a few weeks.
The story surrounds rescuing folks and fighting baddies in general. The environment are large and in 3D, load time are FAST (remember, I’ve been playing on the PSP). The controls are simple and easy to pickup (you don’t need advice). The game instructions aren’t intrusive and you can use the touchpad as the analog control. In other games the analog control has been a bit tricky and perhaps a bit too sensitive but with Rayman movement is pretty smooth and after a couple seconds I had no issues with being able to move around.
Graphics are a poor and I’m not being biased here. Compared to Wario Ware DS, Rayman is pitiful in detail and clarity. Things seem to be a bit too pixelated and I don’t seen any antialiasing. The lack of crisp graphics takes away quite a bit from the game but the excellent gameplay saves the day!
Ubisoft did a relatively good job on Rayman and had the graphics been better there is no way you should’ve skipped this game. As it stands, it’s entertaining and worth the purchase price, so go out and grab a copy.
