Top Wii games: Super Mario Galaxy, Super Smash Brothers Brawl, Star Wars: The Force Unleashed, The Legend of Zelda: Twilight Princess, Madworld, House of the Dead: Overkill, Resident Evil: Umbrella Chronicles, No More Heroes, well I could write a book about all the best games on Wii. Just awesome
No New Heroes
It's No More Heroes.
I don't know any good PS3 games but I can reccommend some PS2 legends. Some other time.
MLB 09 The Show. Or since the season is almost over,wait for next year. Best baseball video game. But the best sports game is always Madden. The season is young,so buy Madden 10 in stores right now. Best graphics of any sports game ever,and is claimed to be the best Madden ever,but they say that every year.
PS3: Metal Gear Solid 4, King of Fighters XII, Batman: Arkham Asylum
Wii: Okami, No More Heroes, Super Smash Brothers Brawl, Madworld, Trauma Center: New Blood, Trauma Center: Second Opinion, Legend of Zelda: Twilight Princess, Super Mario Galaxy
Sorry, accidentally posted it before I was finished. Add Punch-Out!!, Metroid Prime 3 (And the Metroid Prime Trilogy, even though 1 and 2 were originally made for Gamecube) and Mega Man 9 to that list.
