Best casual game ever!

This is a great casual game that I think anyone can learn in about 15 seconds.
A couple of months ago I downloaded this free game called
TrackMania Nations. Most of my friends don't play racing games but at a LAN party about a month ago we all played it for probably two hours and it was probably the best game of the LAN party. Normally I dont even enjoy racing games that much as I normally play FPS games or RPGs but this game really is an amazing thing. The screenshots I think are pretty impressive but here is why I really like this game.

The game has amazing graphics. I'm sure you can see from the screenshots that I have posted that it looks pretty good but there really are some neat effects. The shadowing of the cars is very realistic looking, as a cloud passes over, the coloring of the enviorment changes, everything is highly detailed, the motion blur looks awesome and the cars look amazing. But beyond that, it's control scheme is very simple. All you use is the Enter key to restart your car and the arrow keys to control direction and speed.
And here is my favorite part. All of the cars are the same although they can have different paint jobs. There aren't any brake upgrades or tire upgrades or any of those things. It's just a get in the car and drive. Don't worry about tuning your car for performance or anything like that. This also means that the learning curve for this game is about 15 seconds.

And then there are the amazing maps. The maps are like no other racing game I've really played. It's a cross between skateboarding and indy car racing. You have to use strategy on every corner when it comes to braking and acceleration but then there are booster pads and loops on the track that can send you flying across massive expanses. If you don't hit the jump just right, you'll miss the landing and it'll totally mess up your time. It also has a very easy to use map creator so that anyone can learn how to make their own maps in a matter of minutes which means that there are tons of maps out there to play. I've only played the same map twice at most while playing online.
