I bought this game for my PC last week and it kicks ass. I beat it today. It was fun... But so short. I beat it in like 12 hours, and that kind of disappointed me.
I also thought it was a lot easier than the other Tim Shafer games I have played (Monkey Island series, I never played full throttle or Grim Fandango, so I don't know if the comment applies to them or not).
If you want to pick up a pretty sweet platformer/adventure game for $30 on the PC, I totally recommend this though, the story is hilarious, and it is a blast to play. I think they are still doing a deal at gamestop.com where you can get a free tshirt with it, which is awesome.
