Visually the game has a charm of its own; it’s colorful, vibrant and extremely soothing to the eye, and most of the cars as well as tracks/environments (love the water effects) are well detailed and even though the game doesn’t go overboard with the motion blur, it still manages to convey a good sense of speed. Unfortunately, I didn’t feel the same way about the game’s musical score, which was a bit too slow for my tastes and the fact that I couldn’t upload my own tracks into the game was kind of a downer.
At the end of the day, I would definitely recommend Trackmania United as it’s one of the few games that has effortlessly managed to traverse the boundaries of age and sex with its universal appeal. If that wasn’t enough, the game boasts of one of the best online communities where you can interact with other players as well as download some of the gazillion user made tracks out there (free of cost) increasing the game’s replayability by leaps and bounds.
You CAN add your own music to the game - just convert it to MUX and copy it into the appropriate game directory - the music will then play during the gameplay.
