Obviously i personally think that seeing the world effected by the main quest would kind of take me out of my own role playing and give me a reluctant sense of responsibility to do a quest i don't feel like doing yet. An example would be seeing oblivion gates all around Cyrodiil in Oblivion. That is kind of what i mean in question 2 in terms of actively starting the main quest. Obviously you need to have some motivation, but nothing actually drastically started until you saved martin from Kvatch. I liked that because it let me have a period of guilt free adventuring before i started on something that would effect the future of Tamriel. I just think being swept down a main story would be a waste of the little things like blacksmithing and farming and mining. But again, thats just me. The purpose of this is to hear what the majority thinks.
