michael, I'm with you 100%. I downloaded 20 hours of Unity videos 3 weeks ago because I think enough is enough. I've already started the slow transition, although I'm hoping that a c2 export becomes commercially viable while I am a Unity noob.
Like you say, though, a functioning export appears unlikely in the next 12 months - at least for fast paced games (which is one reason why Umbra is so slow, I just accepted the c2 limits when u started). I admire the work done on c2 but I am not sure I only want to spend time on making slow non-action puzzle games.
Back on thread - have Google acknowledged a limitation or made any progress with this yet?
