Halo 2
Halo 2 allows up to four players to play on the same console or up to sixteen over Xbox Live. The game was influential in changing the way games played over the internet. Before in most online multiplayer games, one player was the host who used their own connection for the game and chose the settings, game type etc. In Halo 2, and most games since, players choose a type of game they want to play and the game matches them with players of their own ability on a randomly chosen map.
