Top 20 games sold worldwide in 2007 and 2008

[Esmoreit]

A safe bet would at least be looking at:

Wii Fit
Mario Kart Wii
Grand theft auto 4
Pokemon-games
Halo 3
Call of Duty 4
Those are sure-fire top 20 games.

Then below you'll have to look at Mario Galaxy, Fable 2, and many I can not recollect.
