The demo is available to the public now, you can download it through Steam. I've been playing it about a week now as I had it preordered and it is the most fun I've had gaming since playing the original Monkey Island games.
Is anyone else playing it? I imagine modders and mappers are going to go nuts for it. And Valve is well know for improving their games for years to come so it's deffinately a game I'm going to adopt in a big way.
