This is from the Gamespot article: Fighting Jam is a two-on-two game, but you it isn’t a classic tag battle setup like some of Capcom’s previous games. Instead, the game lets you choose which fighter you want to take into battle before the start of every round. Characters maintain the same fighting styles--and in some cases, the same character sprites--that they had in their original game. The game will use the standard, Street Fighter-style six-button setup. The character list currently looks a little thin, but Capcom has only announced two fighters from each game. Representing Street Fighter II are Ryu and Guile. Demitri and Felicia appear courtesy of Darkstalkers. Though she appeared in Street Fighter II, as well, Chun-Li is paired with Yun on the Street Fighter III side of things. Street Fighter Alpha brings Guy and Sakura into the fray, and Red Earth provides Leo and Hauser. The game will contain additional hidden fighters. ahhhh very interesting concept....again capcom has created another type of team-like game play. im glad it aint strikers though. im sure the hidden characters are the likes of Ken, Morgan, and Akuma or Bison. But this is CAPCOM fighting jam, so u never know, there could be spiderman and other marvel dudes too...so far, very interesting... That was how the system in Rival School's was. You could choose who you wanted to play as before each round. It's nothing new. But Capcom did come up with it.
