1. Now with perks, weapons are more differentiated than OB, instead of Axe/Blunt and Blade, there is now perk paths for Daggers,Swords,Axe,Mace, and two handed weapons(3 types I would assume) That makes for at least 5 more true weapon choices than OB, no longer will Axes and Maces be the same thing but look different.
2. There were 84 "perks" in Ob that you could not choose, now there are around 170(based on 9 or 10 perks per skill) that you can choose.
3. More combat choice and freedom
4. Alot more towns, OB had no minor towns with 10 or more buildings, now there is 20 or so.
5. More varied look, now with 8 dungeon designers instead of 1(I still am amazed there was only one for OB, damn that guy must have worked alot of overtime!).
In addition to these things(which I really like so they stand out for me) there is crafting, random type quests, dragon shout skills,etc.
What do you guys think? Are there others like me that feel they are getting more with Skyrim than Oblivion, not less?
