Reasons why Halo 3 is the easy winner:
- Madden while a always strong seller is not a Halo 3, this is the game that will come closest however.
- Mass Effect, will have strong sales (I'd say inline with Bioshock) but won't be even close to Halo 3. My number 4 from the above list.
- Uncharted... wha? My point exactly, it better get real big real quick (forums don't count, I know, shocking). My last place.
- "Wii game", if by non-bundled Wii game then Mario, easily. When you think Nintendo you think Mario, and many of the "casual" and not so casual Wii owners will grab the new Mario game. My number 3.
- UT3, 5th for you. Reasons why? Its a hardcore FPS with really nothing new but really nice graphics. UT2K4 players and then some new PS3 players will pick this up, it won't come close to top PC seller of this year and I don't think it'll do that well on the PS3 actually. Xbox 360? Halo 3 rules that world, 'nuff said.
That is why Halo 3 going to be the top seller by a long shot of the games on the list. However, I think the "surprise" in sales will be the Orange Box. HL2, EP1, EP2, TF2, and Portal... amazing deal to all the console gamers out there. Amazing deal to PC gamers and TF2 is going to be very big in the multiplayer PC world for FPS games I believe. I think this might when it comes to collective sales by the second best selling game of the year behind Halo 3, though forever hard to know because you can expect a lot of sales through Steam for the PC.
