I would say its totally seperate to PS3 and 360
Those are both hardcore gaming consoles, focused on the all round experience. Wii is focused on (quite cheap) pure fun, will be a lot of fun Multiplayer and with non gaming types. The graphics are absoloute pants, were talking no better than Gamecube (as far as I can tell). Depends what you want out of it and what sort of gamer you are.
