AVWW is not an easy game to define, I've noticed. In general games that are so non-linear are difficult to write synopsises for.
Something else noting how the game has evolved due to the interaction between developers and players. Always my favorite thing about your games, yet it's the hardest thing to convey to someone who isn't familiar with you guys. Too bad you can't just put "Seriously, we patched the game nearly every day. That's how awesome we are."
