I was an mmorpg'er for a long time but I got sick of the social aspect, dealing with obnoxious idiots and the way that you are expected to play a certain class a certain way with a certain build. I also began to despise the constant gear grind and lack of depth. (WoW)
So, I decided to go with single player RPG's. Skyrim is the first single player RPG that I have ever really gotten into since I began playing mmo's 8-9 years ago and I have never looked back and never will.
I love being in my own world where I am left to my own, undisturbed, imagination and privacy.
