Back when Sega took care of their IPs, Phantasy Star Online was one of the best franchises they brought to the West. During the GameCube era, PSO was released to the console in an episodic format, very different from the one we are used to nowadays. One of these episodes, which were usually full games, was C.A.R.D. Revolution, which departed from the gameplay of the previous installments, focusing on card turn-based combat instead.
