Just read the gameinformers for the game
Everything looks very nice from the pictures and they gave a lot of detail on the many game mechanics.
1.A new language called the Dragon Language has been included into the game, the trailers song is in that language.
2.You can wield two swords at a time.
3.You can fire two different spells at a time. Like dual swords you can place a different spell for each hand.
4.Cool random instances!! Example given from book is if you dropped a sword in town it would a) just be forgotten there, b)a child might pick it up and run to you asking if you dropped this and would like it back, or c) two men might reach for it and begin to fight over who should have it. This is just an example but you can see how this can lead to interesting things
5.If you killed a shop owner that had a quest for you then the shop owners wife/husband or child will take over the shop and might offer you the same quest but out of hate for killing said person.
6.The game learns from how you play and runs random scripts accordingly, if you trained your magic skills up high you might be offered a dual by another mage that would not of happened if you leveled your melee skills. Also when entering a town someone might come to you asking for help because you are a good person and if you agree then the game will look at your map and pick a place you have not been to yet and place the quest there.
7. DRAGONS!!
8. Also gave info and the graphics engine in the game and stated that when snow hits the ground it falls naturally on objects and is not a pre-rendered texture. So I am guessing that if you dropped a object on the floor in the snow it will slowly get covered. It also states how the trees and there leaves and branches move on there own and many random creatures that will wonder the land brings the game world to life.
That is just some of the many ++s given and I can only hope it will be a lot better 10 months from now
