Just finished NWN2 and the expansion. I think there was one crash throughout the entire game. Of course, I updated it with patches before playing.
Jade Empire on the other hand from Bioware, which I've just started playing (after getting it for like $10 on gogamer), has this annoying bug where you can't see see your character/NPCs the first time you load it up. There are no still patches for it after all this time.
At least Obsidian maintains their games.
