Obsidian Entertainment developed FO:NV. Your rage is misplaced.
You don't seriously think that Obsidian did whatever they wanted with Bethesda's very expensive mega franchise and just chucked the product out there
when they felt it was done without Bethesda breathing down their neck every step of the way. Bethesda also being ultimately responsible for the overall
quality of the product. So yes, Bethesda are to be blamed, for not making sure Obsidian made THEIR product live up to whatever standards it should of.
...and if they did, and the way it was released/patched was up to standards...then my friends, then there's cause to be afraid - very afraid.
