and one major different was the map.. first of all it was just sad to see the map decreased that much.. half the map in New Vegas can't be explored... its just there to make it look bigger..
anyways my major issue with Vegas.. was the fact it never felt like a real waste.. a big world.. cause every corner you turned you would be at a new cave and a new quest.. it started feeling like an arcade game to me.
thats what Oblivion did so well.. you felt that you were in this huge world.. cause it wasn't all so compact..
I'm writing this because I saw an interview in which Todd said you were making it more like New Vegas when it comes to the map..
I hope not all the way.. just the feeling of exploring the waste.. exploring tamriel.. that was gone in Vegas.. completely
