Metal Gear Solid 4
Grand Theft Auto 4
UEFA Euro 2008
Mario Kart Wii
All of the games chosen were played to completion or enjoyed hours of co-op play with friends and family
Omitted games were either briefly demoed or never finish the game to completion, for example, Super Smash Bros and Devil May Cry 4. I played a bit of Super Smash Bros and Wii Fit at GDC San Francisco, and I never completed Devil May Cry 4.
I am a hobbyist, do not have access to all the games.
