Hey there. I know of at least two games with a Digimon cast right now. There's route_29, which only has my Hikari here, a Miyako, and a Takeru currently, but we'd love to have any other Digimon characters there. We haven't really been as active these past few months as we could be, since school has been kinda horrible to two of us and work was horrible to the other one, but we're starting to pick up steam again.

There's also dramadramaduck which has an Izumi and Kouji from Frontier. I haven't really interacted with them much (was planning on apping a Digimon character but never did), but they're there if you want to join a current cast with more than one person in it.
