Rayman 2 -
If you\'re into platform -games, this is your heaven. Great graphics, deep atmosphere, long game ( 20+ hours ), great replay-value etc.
AC2 -
If you\'re a serious Mech-games-fan, this is for you. You need to love Mech-games \'tho, as the game is friggin\' hard ( will make you pull your hair out ) and complicated ( if you want a balanced, good mech, you need really to think what parts you buy and how you upgrade your mech ). IMO, AC2 is very good game.
Z.O.E. -
Fast action - this is a mech game also, but much easier than AC2 and more pick-and-play kinda type. The battles are the fastest in console-gaming history ( I believe ) - and the graphics will blow your mind off. Plus, you get the demo of the wonderful Metal Gear Solid 2. It will provide hours and hours of gaming-time.
