There's no Steam plugin or anything for C2 yet, so everyone put your games on Steam so there will be more demand for a plugin! (there is this thing [>] but no idea what to do with that.)
Yes, Steam is going to be my targeted platform as well, though it will be a few months. Hopefully, I can get a thread going within a week or two.
But yeah, I'd love to see Steam support. I mean, not everyone is making mobile games, or at least that's not our main goal, so I'm with you on this one.
