RPGs were fun when I was younger and had time, now they aren't, because they're all inherently just massive time sponges, regardless of the game itself.
I really pity those who actually took Skyrim as some kind of serious RPG, because like Glad said - it lacks everything that defines a good RPG, so the only thing you should do in it is play for shits and giggles. I'd also just add something which no one really seemed to have noticed in it - the fucking stupid as shit AI. The combat boils down to you either overpowering them so much that they can't do jack shit against you, or you exploiting their stupidity to beat them, I mean just look at the dragons and tell me they're "challenging". They're meant to pose a serious threat to you, so you can feel the story better, but all it boils down to is "lemme fly in a circle for 5 mins, and then come down so the MC can hit me better, since he obviously can't aim for shit and requires special help".
