What Will Be The Best Selling Game This Year?

" I don't care. I play games based on the opinions of others and my own, not their sales figures. "

StarCraft II.
 
Do not underestimate the strength of 50 million South Koreans.

Don't know and don't care. Though I'm sure that the best selling game won't be any I'm interested in.

Either Starcraft II or Super Mario Galaxy 2. People really really overestimate Halo sales. Traditionally, Halo games perform on par with Call Of Duty games, and Halo: Reach will be an Xbox exclusive. Starcraft however, is a world renowned franchise by the developing studio with an 11 million person population MMORPG, and Nintendo games almost always outperform other consoles in regards to sales.
