How much would halo 3 sell on wii?

[MikeB]

I don't think it would sell much, I think not a million seller.

1) The most vivid Halo fans already bought a 360 to play this game.
2) The core game isn't really that good (IMO), downgraded graphics and weaker online, would be less appealing.
3) Relatively a lot of casual gamers not interested that much in FPS gaming. Current Wii users mostly buy party games and Nintendo published games. The more hardcore Wii FPS gamers probably own a more capable secondary (/primary) console or a PC for playing FPS games.
