I think my problem with Skyrim is the weak writing and quest design. There are a few standouts but overall most of the quests feel so generic that the Radiant generator probably could whipped them up. I was extremely disappointed in the quality of the Guild quests, the Thieves Guild was the only real standout. It's certainly a huge game and there is a lot to explore but often times the gameplay systems and quests feel rudimentary.
None of this mattered to me, all they had to do right was the dungeons, and they came out perfect. I cleared dozens and dozens of them and with the exception of a few samey draugr locales they were all great. As far as I'm concerned they can do away entirely with all the RPG trappings (which they've never been good at anyways) and just release a dungeon crawler/loot fest (though maybe that's all the recent Borderlands talking).
