Well some of us ... veterans here, remember also what kind of really shitty publisher Bethesda was. They published a Star Trek game and well, if you think Fallout 1 fans can be pissed, you havn't seen them. Bethesda had a track record of screwing developers in the past, it seems they improved on that front. But there sure have been casualties of gaming companies that got really burned by Beth.Im not gonna go through this thread in its entirety but im pretty sure Bethesda hasn't saved single player and this isnt anything more than a cheep marketing ploy.
That said as much as we all love to shit all over Bethesda. A lot of their published games are excellent these past few years. Hell I cant truly remember the last bad game Bethesda published.
This is just pure speculation, but I have the feeling Bethesdas or Zenimax long term goal is to become the next EA. Next to publishing they also started to buying companies, like ID Software and simply assimilating them. It seems that the experience by ID had with shooters kinda helped them with Fallout 4, if the rumors are to believed.
Now I am not sure if that will be a trend for them or not, but it seems they know that Elderscrolls and Fallout alone, won't do it for the future.
