Yeah, but... They kinda suck. And their fans suck even more. They like dumb shit. Although Fallout 4 appears to have been too dumb for even some of their more hardcore fans start to be pissed off.But they had so long to work on fallout 4 and so more experience with other projects !
And they worked so long on Fallout 4, but with how many people? Bethesda (the developer) never really expanded, they just don't have many people working for them. Especially not in the writing department, or in Q&A.
