This is the first time the series has tackled fully functional four player co-op, with previous games having incorporated multiplayer co-op play with limited functions. With the four-player co-op some fans have compared Sonic Superstars to the New Super Mario Bros. games. Much like Nintendo’s platformers, Sonic Superstars has four different playable characters: Sonic, Tails, Knuckles, and Amy Rose. However, this is limited to drop-in local couch co-op, with Takashi Iizuka, the creative officer at Sonic Team, explaining why.
