I put Skyrim in my backlog years ago and never got around to it.
I played Oblivion when it came out for PC. I bought the expansion back when it was on a DVD and don’t think I ever played it.
I did the same thing with Morrowind. Bought it on release, played the hell out of it, bought the expansion and never played it.
I played through Daggerfall multiple times, but that was when I was young, didn’t have many games, and obviously way more free time.
I think these games are just a bit too big and time consuming for me to really sink any time into a second time around.
