A game based on roller derby is something that never occurred to us, but it seems incredibly obvious now that someone's doing it. Frozen Codebase announced Jam City Rollergirls, a WiiWare game based on women's flat track roller derby and featuring real roller derby leagues. This is the second "official," licensed WiiWare game for an unconventional sport that we can think of, and it's far less disgusting than its contemporary.
Frozen Codebase plans to release the circular skating and violence sim in the fourth quarter of this year. Jam City Rollergirls will also be at PAX this weekend for the curious to give it a spin.
