The more details that are released about this game, the more impressive it looks. New details have popped up on the Internet on what we can further look forward to from this awesome game.
In Skyrim there will be new magic in the game called Dragon Shouts. Whenever you kill a dragon in the game you will get its soul which allows you read ruins that you find scattered across the land. Once you decipher the ruins, you will have access to the Dragon Shouts that are different to usual magic spells. These Dragon Shouts will allow you to do magic like teleport or do a force push. Deciphering this code could also be some sort of puzzle too.
Also making a return to Skyrim will be Enchantment, this was an ability you could achieve in Oblivion once you were granted access to the Mages Guild. Enchantment will allow you to infuse any weapon with any spell effect you already know to make it more powerful, spells such as Invisibility or even the ability to breathe under water.
Enchantment will also work with any accessories you own, be it a shield or a necklace. The only way you could Enchant an item in Oblivion was with the captured souls of fallen enemies which you stored in soul gems. This could be where the souls of slain Dragons would also be useful in Skyrim!
More details have also been confirmed about the ‘Radiant Storytelling system’. This basically is a game changing addition depending on your style of play. As you play through Skyrim, all your actions will have a affect on the game and the Radiant AI will adjust the quest/story to suit your play style so you get the best possible experience. This will make every play through of this game unique to the player.
