Wow. GET GET GET the goty edition!
Ive searched quite a lot for the disc, then found it second hand and bought it online.
Installed the add-ons from the start and never had any huge problems.
A crash once in a while with numerous enemies on the screen (which is normal to happen, as the game itself crashes every now and then).
Then i installed the game itself on the hard-drive itself and it run 3 times as quiet.
Great, thanks for the informative reply. I'll probably end up buying it. It's good to have an actual hard copy of Fallout 3 and all the DLC. I bought the downloadable version of Fallout 3 and the DLC from Xbox LIVE. As far as I've experienced, there's never been any crashes or glitches at all. It's worth it for the disc though. I need it.
