1) Option to disable kill cams.

2) Respec before leaving Helgen keep

3) Optional 1st person view in all forced 3rd person circumstances.

1. Less linearity in the individual level design layouts and the like. Such as giving the player more ways to approach an objective.

2. More of a focus on choice and consequence, so our actions and playstyles actually affect the world around us.

3. More focus on proper quests rather than radiant questing.

This sums it up for me.

1. No Quest Markers, but more detailed journal.

2. Choice and consequence.

3. Quests and factions with more depth.
