Played only Vanilla, with mods the experience can be drastically improved. Beware of the insane number of bugs (even in the GOTY edition) and crashes due to Bethesda being Bethesda. Although I consider Fallout New Vegas to be superior in most if not all ways to Fallout 3, I still prefer it over the 'better version' due to a simple yet enjoyable story, plenty of content, entertaining stories and very impressive and depressing locations, filled with death, despair and also teddy bears in compromising positions.
