Yeah, I heard Vista sucks and that's what my system uses. Plus, I've read negative reviews about Vista and had no idea what was being talked about. What is the difference between Vista and XP???

The embarrassing thing about Fallout 3's achievements is that you can 'add' them via the console. I'm not kidding, 10 minutes with the game you can give yourself all the DLC achievements as well, even if you don't have the expansions. I'm not sure if its a bug or a feature XD
