I have been playing America's Army for a while. Go to aaotracker.com for full free downloads. It is a game the Army puts out, that's why it's free.
Graphics are good, many maps, a new version is due out this winter(?) There is no respawning, you respawn when round ends, so being tactical is a must.
Just baught cod4, the respawning and running around is chaotic at times. No team killing so you don't worry or care where shots go. Singleplayer has great graphics and action.
I saw a sports car racing game on youtube, motorsport foranza 2, looks good. Many cars to choose from, different tracks.
