Funny, I don't see a lot of better looking games then the 8 year old metroid prime.
A high budget wii game aka Nintendo game(it's a synonym) usually have a lot better quality then any other game. Just look at super mario galaxy, metroid prime 3, zelda: the twilight princess, super smash. bros brawl. Find me one game on PS store that looks better then the games I mentioned. And graphics go far further then just hardware...
Ps: It's not hard to make a better looking game on ps3 then wii games. Stop spouting bullshit because the hardware makes it easy to make better looking games. Your average HD game costs a lot more then a SD game... That's a fact and the only thing that matters in your pointless discussion. Little big planet doesn't have much content, well it does have much content, but that's because YOU can make levels and share them.
