Just returned from Skyrim, I only played this game a bit a year or so ago to work on my fighting skills in the Arena then had a save game malfunction and went back.
Some GOOD things I've noticed;
#1 Black and white, good vs. evil. Hurray!
#2 A Waterwalking necklace as well as the boots. Whoot!
#3 'Smarter' NPC's and dialogue. *Fist pump^
#4 Longer and deeper quests. A LOT longer and deeper.
#5 As Master of the Fighters guild you get PAID to LEAD. "Duh!"
A lot of players on the Skyrim forum rate Oblivion as the weakest in the TES series. What? Why the HELL do they feel THAT way? I love this game almost as much as Skyrim and have since my aborted first attempt. WTF?
