jitspoe found it ,on a post when we were talking about the unity game engine (what that game engine that made the game on paintballgame.com ) plus once i heard about unity i started to use it and work with it. its simple to use for creating 3d/2d games for any platform. thing is that you need to pay 400 to get an exporter for android, ios , ps3 , wii etc free ones are web player, windows platform, mac and flash player.
tbh its easy to use try it out.
unity3d.com
to get started i'd suggest watching a couple tutorials on youtube.
