Don't worry bud. It'll all be good.
I've been hanging on here for ages now, basically waiting to see some active members again so that I can leave, knowing it's not just going to die.
Very gradually giving up though. I'm glad you see me as a valuable member here still though, I'm checking back once or twice a week.
However, it has always been the same. When one group of coders leave, another group eventually comes. And there's still people around - James is a busy guy, but he's still at it (slowly). As for AQ3D - the game is (technically) nothing like AQW - it's a whole new area to investigate and eventually someone will do so. I can't see anything happening very soon though.
