- Locational Damage-gives criticals and different effects based on where your attacks land, enemies can do the same to you.
- More Dynamic Injuries-Everyone suffers from broken bones, bleeding, frostbite, etc. Spells can only heal you so much and you must seek emdical attention for large wounds fast or you will die.
- ASIS-Enemy AI uses potions and the amout of enemies that spawn has been vastly improved
- Ultimate Follower Overhaul-lets followers level and increases the number of followers you can have (don't get anymore then 5, it's really lame running around with 15 lvl 81 characters and clogs doorways)
- Deadly Dragons-more dragon types with more shouts, higher lvls, etc
P.S. Skyrim is now populated if you did this right, I frequently see realistic amounts of wildlife.
