It's still Wii Sports. Either way, you're paying money for the game. The Wii could have cost like $199 or even $150 but it wouldn't have made that much profit. That being said, Wii Sports would be that $50 leverage that is incorporated into the $250 price tag. I still don't get it though, Sonic the hedgehog was a pack in game but I don't see that 10s of millions of sales that it supposedly had in the charts. The game sales are insane though. I mean, Rockstar is probably drowning in cash.
Edit: Nope, it's tetris...don't even try GTAV. You'll need another good 60 Million more.
