My brain kind of wants to play through Morrowind and Oblivion before Skyrim.. but honestly,, just like Daggerfall now.. I've so overplayed those games that I can no longer get very far in them. I start them and then get bored because I've done everything I could in the games before.. there's nothing left to explore or do..
The novelty eventually wears off. I'm the same way. Loved Daggerfall and Morrowind, couldn't get past the level/loot scaling in Oblivion so didn't put more than 20-30 hours into it. Really hoping Skyrim captures the production quality of Oblivion, the static world of Morrowind, and the depth and intrigue of Daggerfall. In terms of replay, I probably will replay Daggerfall when Lucius finishes his XLengine remake for it. It's looking fantastic so far!
