This is actually something i have been thinking about for awhile.
What game do you think will sell more and what will be the better game?
I personally say Zelda will out sell Brawl in America because Zelda was the automatic launch title that almost every "gamer" picked up. I think Brawl might now exactly do the same. Don't get me wrong, i think that Brawl will completely beat Zelda in worldwide sales.(Mostly due do to the fact that In japan, zelda doesn't sell extremely well)
But i do think that if people that dont have wiis had to pick up two games when they actually grab wiis when brawl comes out, i think it will be zelda and Brawl. They will get brawl for multiplayer, and zelda for single player. Plus, maybe even a few retailers will drop the price of zelda for the 2007 holiday season spiking sales slightly.
What are your opinions?
