They didn't say Beth made FO:NV. They said it used their engine which is true. Although seeing everything the game has to offer is a challenge I'm willing to take lol
Ironic you tell everyone else to read it closely.
Fo 3, made by bethesda, did not have nearly the amount of fail as Fo NV, made by obsidian. So taking up another companies incapability to use bethesdas engine is not a good example to begin with, unless you think bethesda made Fo NV. Which either means they are idiots or idiots in another way.
