Very cool if you like playing on an iPAD with very small screen ( not for me though) I chill out and play on my PS3 through the sound system and on a 50" screen in HD, firkin AWESOME
It is funny that I play RBION on my PS3 and look at it in the kitchen (and Vice Versa ) cool game and great in both formats although on Pinball Arcade it is a lot easier me thinks
