Will different terrains produce different footstep sounds, will sounds vary on the same type of terrain?
when our character sprints, can we hear him/her breathing?
if he's low on fatigue, do we hear gasping for breath? same goes for surfacing from the water.
Will the swim speed still be broken like it was in Oblivion?
Will movement speed be slower when going uphill? Will it be faster going downhill?
Will there be echos in caves and other similar places?
Will sounds be different when we strike different things with our weapons? In other words, when we strike dirt, will it sound like we're striking metal or stone?
Will we be able to choose our character's voice when he makes noise, since there are multiple voice actors per race? (70 voice actors means 7 per race, 3 or 4 per gender of that race).
