Mission Equitation Online is a Massive Multiplayer Online (MMO) game from France. The game CD installs a variety of screensavers and wallpapers as well as the game data. The game itself opens up in a browser window so that the player can log in and play and it is entirely on-line. There is no single player practice mode that the player can use on their own machine.
The game was apparently very popular in its day, archived web pages from the game's web site show the number of members exceeded 264,000 however that web site is no longer active so the game is no longer playable.
The game's pre-release web page promised: "You'll be able to take care of your horses in the stable to forge a real bond with them, and enjoy the 3D game environments during walks in total freedom! Mission Equitation Online is more than just riding online game is primarily a community of passionate people like you. Also we have an in-game chat feature so you can chat directly with your friends."
There was also a trading card element associated with the game, players purchased credits to buy cards that gave them additional horses, there were twenty-four in all.
