I've seen lots of posts from people complaining about how they hate how the difficulty of the enemies/quests increases as your character levels up. Particularly when discussing the Kvatch main questline - many players have had trouble completing it when they were beyond level 10.
Personally, I love leveling. It means that even trivial quests can be a challenge. One thing that bored me was when I had completed about half of the quests and/or the main quest in MW, all other quests were just too darn easy.
Oblivion takes care of that problem, but many of you disagree with me! Vote and post here!
I like that the monsters get harder, but i'm lvl 12 and bears are kicking my boat, i dont think this should happen, there should be a certain lvl they can get to, and then that is it, so that some things are just easy when you get a higher lvl, well rats are easy and ghosts are easy but besides that, it is much better than morrowind though where there was a ponit i could kill anything with 2 swings. So I would rather have bears kicking my boat.
