Some Infos:
-Level scaling.
-You level up your skills through use.
-No traditional attributes anymore (str int etc.). You have health, magicka, and stamina, which increase automatically at level up and can be improved individually at level up as well.
-No predetermined major or minor skill selection (or "class" selection). Everything is entirely based on how much you use each skill.
-When specializing in a few skills, you will level up faster. When using a broad skillset, leveling will be slower (seems to be a way to prevent problems with the level scaling system, i.e. skilling up non-combat skills in Oblivion and becoming useless as everything still scales up)
-Perk selection, Fallout-style, upon level up.
-Kiting is more difficult as backwards movement speed has been significantly reduced.
-Each of the player's hands is set up individually. Sword and shield, dual wielded weapons, one weapon and one hand for magic, each hand with a different spell ready, or both hands using the same spell for a more potent effect, etc.
-There are 18 skills + perks for every lvl you aquire.
-Leveling is quicker at the beginning but much slower at higher levels
-There is a soft lvl cap at 50, you will still be able to gain levels but it will slow down dramatically
-If you kill a shop owner a family member will take over for them
-Dynamically logs your play styles and quests/NPCs react accordingly
-You can sprint
- HUD free first person view
- six or seven different enviroments: rugged mountains, tundra, glaciers etc
- Five massive cities
