Fallout 3 is the buggiest game I've ever bought

[Lazarus and the Gimp]

Issues so far-

1- Crashes like a bastard.

2- Prone to graphics breakthrough and flicker even after updating drivers.

3- Some side quests appear to be impossible to complete due to "Speak to...." tasks failing to trigger the necessary dialogue paths.

4- Disappearing/suicidal NPCs bugger up the plot.

Not impressed. Needs patching, badly.
