Skyrim would have to be my favorite out of all of them. I liked the graphics and the plot line with this one. It has a mass amount of quests and infinite levels in the game.
I played a bit of Skyrim when I had a gaming laptop that worked, but I didn't really play enough to get into it too much. I had other things distracting me or other games I admired more. I'm not the best at RPG-like games anyway.
