This person has zero IMDB credits. Call me after making literally anything even remotely approaching the quality of anything Bethesda has ever sneezed out.
Does he maybe have some semblance of a point about NCR and New Vegas? Sure, but if that makes it a 'bad show' that 'no one will watch', please let me point you at Star Wars, which jettisoned its own extremely substantial extended universe to the chagrin of long time fans and is doing fine.
Can't you just, like, look at it like anime or like Douglas Adams?
Yes, we get multiple iterations of more or less the same story in different mediums. No, they aren't exactly the same. Is that a problem? Does the Ranma 1/2 TV series have to match the OVH or they're both shit?
Do I have to choose only the Hitch-Hiker's Guide books, or the radio series, or the show, or the movie? Am I not allowed to enjoy them all?
Is it really more economically viable to make a living being an entitled and cynical jackass about other people's work than to go make your own?
