I'll hazard a guess; nearly all. From what I can tell, development companies get the short end of the stick. For example, a game released at somewhat the same time as these, Vampire the Masquerade: Bloodlines, was released with a half-finished engine and was rushed so badly that it was too buggy to play. One official patch was made but the development company, Troika, made almost nothing from it and went under. It wasn't until user patches were made that the game became playable.
I first played Bloodlines years after it was released so never experienced it without the user-made patches, but yeah: even then you could see the point where they ran out of time because there was a marked difference between the first half of the story, which was interesting, complex, witty etc and the second half which ended up being pretty much a straight shooter. Needless to say I found the first half a lot more enjoyable to play.
Although "when's it ready?" has been a constant rallying cry through the development of D:OS II and one I've sometimes joined in with, it's been nice that Larian's former "enjoyment" of having a publisher isn't a thing as it has noticeably affected their games too, albeit not as badly as some.
