Felt like stirring the pot?
Obs got NWN & Kotor sequels because they where the only other game company that makes story driven rpgs. Honestly name another company that makes story driven RPGs beside Bio and Obs. That's not to say Obs wouldn't of got them had there been other companies, it's just Lucasart and Atari didn't have many choices. As to why they would accept, why wouldn't they? Most devs would love to get a start up with two successful franchises. As for NV, I think it was quite natural for Beth to look to Obs and a no brainer for Obs to accept. DS3 though, that was out of left field.
People love to blame the Q&A teams for this, but I would bet my house on most devs knowing about the bugs before the game ships. In any case an easy explanation would be Obs trying to do too much, not saying enough is enough early enough.
