So far the only PS3 game we have is Oblivion.
I'm not into Sports or First Person Shooters, so the choices are limited now.
Thought about getting Sonic, but then I'd never keep my son off the PS3, he's really into Sonic the Hedgehog lately (have a bunch of them for the Wii/Gamecube).
So for now, it's Oblivion for me, and the wife is still playing FFXII.
