Cool news about the demos features - think they're shooting for the machinima fans?
Source seems to be so customisable, I think it's great they're thinking of the mod community (which, really, led to HL1's longevity) - my only worry is how complicated it will be to actually do anything! If i make a new texture do I have to add it to an attribute libray, give it sound properties, physics propreties, bullet shrapnel properties?? From what I've seen it's all cool and customisable, but kinda scares the bejesus out of me too.
Um, ok, that got wierd and OT.
