Alright, so let's settle this right now. Bethesda fully developed and released the engine for Fallout 3. They turned it over to Obsidian who, with the help of some of the original team from Fallout 1 and 2, modified it to create Fallout:New Vegas.
BUT
Do you really, honestly, believe that Bethesda would let them release a game - with OUT checking it out first? No way. It's a Bethesda game, through and through. That's why their name appears first on the title screen, and Obsidian's second.
People know bethe did QA and Obsidian still gets blamed for bugs.
No its not a bethesda game, it may use their engine but that dosent mean jack [censored]. If I lend you tools to make something, what you make isnt mine.
Bethesda's record as a publisher is bad.
Brink was unplayable.
NV was buggy, I love it but admit that.
WET was forgetable.
Rage was nothing special.
Hunted was forgetable.
Then they canceled prey 2 which had potential, and screwed over Obsidian with FNV payments.
