Yeah, it is kind of a bummer that you cannot go back to previous maps. Many people completed the quests of the act and then go on a killing rampage to get xp before continue to the next chapter o.O
I suppose I never really understand people who do the whole "lol killing spree" thing anyway, whether or not from a role-playing perspective. Then again I'm that person who wrote a program complete with its own crappity scripting language to safeguard most of the NPCs in Oblivion because I was fed up with finding settlements to be deserted whether or not an NPC was especially "useful" (though I do have especially not fond memories of spending hours searching for skills trainer Bralsa Andaren who I only discovered afterwards was notorious for being beared to death thanks to aimlessly wandering about in the wilderness).
