I found TrackMania Nations Forever on Steam when searching for free games. Expecting it not to be very good, I didn’t play it for months. Today I finally tried it and was very impressed! As soon as I played the first course, I was reminded of the PC game Stunts. If you’re not familiar with that game, don’t worry. I’ll explain the game. There are four difficulties, each with fifteen tracks. Only the first five tracks of each difficulty are unlocked by default. Finishing a set of five unlocks the next set. There’s also an additional difficulty with only five tracks; these are locked and have high requirements.
You race alone or against ghosts. There is online races, but even then, you’re basically racing ghosts. You can’t physically interact with other cars. While you’re driving, you can respawn at anytime in case you get stuck as well as restart with the press of a button. Some tracks require you to complete multiple laps, but most are one lap in length. In addition, a lot of courses involve tricks such as driving off ramps and aiming to fly through holes. There’s also a level editor in it, which I haven’t tried yet.

 
TMNF looks great. The textures aren’t very amazing, but the models are very nice, and the lighting is also great. It’s not going to drop anyone’s jaw, but it does look very slick. There’s even a mode for 3D if you have the red and blue 3D glasses.
The game is very enjoyable. You can play in short intervals, and it’s very fun. With many tracks, online leaderboards, and a pricetag of zero dollars, there’s no reason to not try this game out! You’ll be in for a treat.
And if anyone does try it out, add me to your TrackMania friends list! It uses a separate list than Steam. I’m MrUser!
