Rivals is a befriending system featured in Conduit 2.
In addition to the Wii's use of Friend Codes, the game features a "Rivals System" in which a player can send friend requests to other players in the lobby of a matchmaking match to add to their friends list without having to exchange the friend codes. Advantages of befriending players with this system includes being able to chat with eachother, and playing with a rival for the first time earns an achievement once. Also, players that have exchanged rival requests can also participate in both public and private matches that their rivals are currently playing.
Up to 64 rivals can be listed.
