Every PC game is different, and the amount of different PC configurations out there are countless. You might have luck with a lot of games, but eventually you will need to troubleshoot if you really want to keep playing PC games. It's just odd that you would rather give up and blame the game rather than trying to fix the problem.
There are thousands of people that managed to play Fallout 3 without it crashing every 30 minutes. I'm not saying the game doesn't have technical issues, it has plenty, but crashing that often is something on your end, not just the game.
I'm aware, but a lot of people seem to have equal amounts of problems with crashes (although not as severe). I'm actually suspecting FO3 just crashes normally (IE, to desktop), but my PC configuration somehow messes up afterwards.
Also I have the game on the 360, so I'm not abandoning it.
