This was a triumph. I'm making a note here, huge success. It's hard to overstate my satisfaction. I'm a Mac user but I installed BootCamp and Windows XP (and Steam) just to try this out, based on word of mouth. It was completely worth it - the most fun I've had playing a game in ages. The story section (which has a number of beautiful twists in it) can be completed in an afternoon, so even if you don't normally have time to dedicate to games it's short enough that you can appreciate it without losing 40 hours of your time to it.
