TrackMania United features a peer-to-peer networking system allowing players to share custom content more easily, and a unified ranking system. On June 30, 2006, TrackMania United was announced, a version that amalgamated all previous TrackMania editions into a single game that includes all the environments from the earlier games, and subsequently future installments of the series.

Nations quickly became popular with almost 1 million registered online players within weeks of its launch ), largely due to the wide availability of the freeware game. The top five players can be seen on the game's homepage. One of the main attractions is the leader board, where players compete for the best times and points. The game contains 100 single player tracks, the earlier ones relatively simple in both design and gameplay, but it is largely pitched as an online game. This free, stand-alone game had one new environment, 'Stadium', and many of the Sunrise edition features, including the advertisement panels, which show ads from sponsors streamed from the internet. On January 27, 2006, Nadeo released TrackMania Nations, also called TrackMania Nations ESWC partly as a promotion for the Electronic Sports World Cup, and also for TrackMania itself. Multiplayer races operate as concurrent time trials players' cars are visible on the same track at the same time, but cannot physically interact with one another.

Players may choose to respawn (retire) at any time, for example if they land upside down, leave the track or get off to a poor start. TrackMania games typically have a time trial format, with medals awarded for beating set times in single-player mode, as well as the ability to submit times to various online rankings. Instead of following the usual trend of choosing a set car and track to play the game, in TrackMania the players can create their own tracks using a 'building block' process similar to games that existed before the first TrackMania game, such as the 1984 game Excitebike, the 1985 game Racing Destruction Set, and the 1990 game Stunts.

TrackMania is a series of racing games for Microsoft Windows, PlayStation 4, Xbox One, Nintendo DS and Wii developed by Nadeo and Firebrand Games. New logo for the remake of Trackmania Nations, Trackmania (2020)
