Excite truck got a 6.8 at gamespot. No surprise there, I played it and it was dull which was their complaint also.
Cod3 got a 7.7 through IGN, who is generally much more lenient than gamespot , which is scary. They said graphics are about as good as a regular xbox, no biggie or shock there, But they did have control issues which is the scary thing about the Wii, trouble throwing grenades through the assigned movement, it wasn't registering 100% and a lot of trouble with some of the more fast paced movements such as melee combat against the germans. No multiplayer and no online, way to BLOW COD3 for the WII.
