That is a bit harsh, I would still buy there games even with tons of issues about them
I didn't even buy New Vegas, but then I'm very sensitive to buggy games. For me the whole experience is ruined by random freezing, even when it doesn't freeze. Just knowing it can happen anytime is a killer of joy. I might buy the game when it hits the bargain bins.
I will criticize Bethesda every chance I get, and I recommend others do that as well. Their reputation should take a hit for all these bugs, especially the ones in FO3 since they remain years after its release.
Their lack of communication is also really bad. Can't they just acknowledge the freezing and say that they're working on it and give some sort of estimate where they are in the process?
The next level of neglect would be if they release a DLC while the original game is still freezing. That means they have been working on the DLC while a lot of people have paid for a game they can't play.
