Trackmania Nations is a fun little time-trial racing game by Nadeo. Silly physics, manic tracks, and not a hint of realism – just what I look for in a racing game! The tracks are fairly short to begin with, though they get longer as the game goes on. I find that the early levels are the most addictive, however, as I play through them again and again at 16 seconds a pop just to get a gold or green medal.
