What impresses me is the giant number of FPS on Wii. We´ve got Call of Duty, Red Steel, Medal of Honor, there are Manhunt and Metroid coming and Brothers in Arms. Than we´ve got Disaster this year and a Red Stell sequel is sure as hell maybe still in 2007...
Games like Prince of Persia, Zelda, even Brawl (which is a great fighter and deeper than some would think...) are very "adult" games to. Driver is coming out and Blur is a game for Experts too as it is Resident Evil 4 and Umbrella Cronicles.
So why should there just be fanboys and casual gamers? Is there a sign on the Wii: "Just for Fanboys and casuals"? The audience changes as the console does. There is not one audience and it never changes...
