I'm a computer game girly man so I have a Wii. Not especially impressed with it's version of FIFA 10. Some respect to EA for building a separate game for the Wii rather than porting the Xbox/PS3 version but they've effectively turned it into an arcade game. It's good fun and they've properly sorted out the online function (it's so much fun being a veteran of FIFA 09, smashing some poor German kid who's playing FIFA on the Wii for the first time despite the fact you're playing as Aldershot and he's gone for Bayern) but there's very little to it. Bit cartoony and frustrating if you want to pretend you're a football manager questing for a trophy on a rainy Saturday afternoon.
I think I'll be getting an Xbox 360 soonish and I'll probably pick up FIFA 10 on that. I'd imagine the Xbox and PS3 versions are still football obsessive Valhallas.
