If you give this game only a brief glance, you are going to see a simple arcade racing game where cars look like toys and drive round corners at speeds exceeding 600 km/h. But if you look under the shell and start probing deeper you shall see that TrackMania is in fact many things and it isn't in fact simple, but rather simplistic.
Do you like hardcore racing where you need to hunt for tenths and hundredths of a second, and even a small concentration lapse can result in a crash when you are on a world record pace? Come on in, there's plenty of that. Do you like to build maps for others to race at? It's easy to do that with a built in editor. Maybe you prefer doing various stunts, such as backflips, barrel rolls, driving through loops or just riding the walls in a car? TM is a perfect choice for you. Just in case you like puzzles, there's a game mode for you where you have to build a fastest way between start, finish and a few checkpoints using a limited amount of blocks. Then again you can just challenge your brain and your very self to try and seek for outrageous shortcuts in others' tracks, as nobody can dictate you the order in which the checkpoints must be driven.
And there's definitely more to this game than I mentioned above, feel free to discover your favourite bit of the game.
One of the best things is of course the community. People are usually friendly, helpful and positive in every way.
