That one caught me by surprise in my last rewatch . I couldn ' t stop laughing . Oh , Emily ! <| sep |> except they barely handed them it . It ' s more like Bethesda handed Obsidian a fuckton of fallout 3 ' s assets and they made some enemies and areas and a good story with it . Even before that , it was because the company most of Obsidian ' s employees were from not anymore , they have a bunch more employees than bethesda now who made fallout ended up almost killing it with a shitty game Fallout Brotherhood Of Steel and a semigood game that didn ' t sell well Fallout Tactics and they tried to start developing a sequel to Brotherhood Of Steel before it was even released for a 2004 release , which got canceled and also got Van Buren canceled Interplay ' s fallout 3 . Then they tried to make a Fallout Online , then Bethesda sued them which eventually lead to an agreement where Bethesda owned the fallout franchise . Then fallout 3 happened , it was a success , then Bethesda let Obsidian develop Fallout New Vegas . So really , Bethesda sued Interplay and got it , and then let Obsidian develop a game for it .
