First and foremost, Elder Scrolls IV was my all-time favorite game. Nothing else even comes close. Loved it. However, I did have a few complaints that I hope are not in Skyrim. The main problem was that even though this was considered a "role playing" game your could do everything in the game. Be the head of the fighters guild, and the mages guild, but at the same time be the involved in the dark brotherhood and become the grey fox. While I suppose it is possible for a "hero" to pull off many different identities and be involved in all, it did take away from the role-playing experience. And in the end, we really had no choice at all as to what was going to happen with the game.
What I'd like to see is something more along the lines with what, don't stop reading after you read this, Obsidian did with New Vegas. I really liked the factions. If you aligned yourself with one, their rival eventually grew to hate you. I think that would add a ton to TES experience. Hopefully this will be considered. Anyone else feel this way, or do you guys like being able to do everything with one character?
Again, I think I've said this in every post. I can't wait for this game! Can't wait!
