Sorry, I'm not sure if I understood this. You want to know if the Droid X360 is able to run CPS3 games? and, if it doesn't, you want to know if there are other options that do?
There's an emulator that plays CPS3 games (Tiger Arcade: http://www.youtube.com/watch?v=fj-CupkosmI
), but I don't know if it's playable on this Android handhelds or not. Maybe you can search the specs of that device of the video and compare, if the Droid X360 is similar then it looks playable.
If it's not enough, there are tablets with better specs, but without physical buttons.
