They were told if they received 85% score on metacritic they would get a bonus instead they got 84% and got nothing. Any human being would be like "okay you guys spent a year of hell here is your bonus" but because Bethesda is run by robots they got nothing.
First of all let's forget the fact Bethesda gave Obsidian an impossible task. Obsidian had only a deadline of a year and a half to create New Vegas. Which is shorter than the average Bethesda project because Bethesda comfortably develops a game for 4+ years but that's besides the point. The point is Obsidian in a years worth of time created a far more intricate and complicated story than Bethesda ever could. Do you know how hard it is to develop a game where pretty much 99% of the population is killable?
This lack of a bonus surely didn't help their near bankruptcy situation. They even had to cancel a project because of this.
Not to mention New Vegas had much more complex quests like the quest "Where's the beef" in the strip where you have to stop cannibalism. There is so many ways to finish that quest. You could kill the residents, kill the father, kill the son, embrace cannibalism, stop cannibalism, sacrifice your companion, drug their drinks. This was just a loving side quest but damn is it detailed.
Your average Bethesda quest: Run to point A to pick up this thing I am looking for then run back to point B.
