I agree, Morrowind's plot was heavy stuff, it's harder to judge Skyrim, the civil war really should be thought of as part of the MQ, the actual Alduin killing part alone was pretty damn short but I genuinely had fun, not much late night pondering of philosophy though
As for my game, I'm about 14 hours into my second character, a Dunmer dual wielder/destruction mage, having lots of fun zipping around in light armour and dealing good damage, so far I've been happy with the re-playability, this character plays differently to my Nord brute.
