This game has way too much too do. And I like almost all of the dungeons I've visited.
I feel like I've done so much. I've got way too many shouts, level 26, am Archmage of the College, Thane of two holds, and am somewhat into the Companions series. But I've only really visited those two holds, and just walked into a third a few minutes ago. Only completed one major faction quest, and there's still more quests to do with it. And barely touched the main quest. I'm 40 hours in and I don't have any skill up to 70.
I've got Assassin's Creed coming on Tuesday. I don't have time for all of this!
