Well what would you prefer? A huge map that is less interactive? Or a smaller map with tons to do?
I would be fine with a map about the size of Oblivion, but much more detailed. And given that they've been working on this game probably 5+ years, I don't think that's unreasonable.
Actually, they've only been fully dedicated to this for about 2-3 years, remember Fallout 3?
I would personally prefer a smaller map with lots to do, but a large map would be fine - as long as it was interesting.
it is likely that the cities will be gone, because it will be like 200 years after Oblivion, and with Oblivion it was the same deal, we lost a lot of cities in there, but really there isn't that many cities in Skyrim
No we didn't. We didn't lose any cities from MW to OB, unless you count Sutch, but that was never around before OB. However, your point about losing cities may be reasonable, because the trailer implied that there were wars going on, so we may see some cities fall and some rise.
