I agree that their games have been shit for a while, I didn’t even think F4 was good, and NV demonstrated that Bethesda shouldn’t be the ones developing the series.
F3 was great at the time, but after playing NV, you can see that Bethesda is interested in creating a very railroaded experience (pun not intended).
However, I think a TV show might be fine, seeing as though the stories of Fallout haven’t been bad; it has just been bad mechanically.
