I don't know, there must be something to it. How can a single-player game generate over a billion dollars in profit and years of enthusiastic engagement from fans without doing something right?
Let them be, they are edgy idiots who want to go against anything "mainstream" so they can think they are above the "plebs". They go against the grain. They are the "cool kids".
Obviously no one buys something he does not enjoy. The fact that Skyrim is still, 7 complete years after its release, still relevant today, speaks volumes about its quality. Unless those edgelords believe that Todd Howard placed a gun on everyone's head to open our wallets and buy the game...
Whether they like it or not, Skyrim IS an RPG, and it IS hugely successful. And no matter what they claim, i am willing to bet it is installed on their systems too.
