Does the world difficulty scale equally with your level like Oblivion (meaning there are no high level areas on the map verses low level areas, it just scales everything everywhere to your level.)
I canít say from experience yet but from what I read yes it is supposed to scale with level mostly. However, some areas are scaled to be inherently harder or easier than others regardless of your level. Also caves and dungeons you enter are not supposed to scale after youíve entered them once. Once you enter them even if you run away and donít finish them are supposed to lock in their level based on the level you were when you first entered them. This is based on what Iíve read and havenít verified it in-game.
How do the level and skill advancements work compared to Oblivion. Do you still have to carefully micro-manage your skill advancement and be very careful when you sleep or end up with a high level character with many skills not equal to your level. Given the way the world worked, this made it very easy to end up with a character that got a lot weaker vs. mobs instead of stronger as you level because the world scaled harder but your skills might not have advanced sufficiently.
Leveling is much simpler. You no longer have to micro-manage to ensure ďefficient leveling.Ē Skill increases are still based mostly on use which is what actually tends to define your characters ďclassĒ in that you get good at what you do however, here is still training and some skill books. You could still end up with a high level character with little magical ability if you never use magic in-game but again this is going to be based more than anything on your style of play.
About the only micro-managing part of skill increases is what power stone sign you are under at any given time. Rather than picking skills at the beginning that level faster than others you can continuously go back to the power stones and switch between thief, mage, and warrior which allows those associated skills to level 20% faster than the others. So if you want to ďgameĒ things a little you can do what I did early on and go exploring under the Warrior sigh to up those combat skill and change to the Thief sign to go into town and sell things and sneak around more to up those thief related skills. Same thing you could go dungeon romping under the mage sign to more quickly boost your magic skills however, sometimes ití just too much of a pain to go back to the stones and change your sign.
Also, you donít have to sleep to level up. You can level at any time after you get the signal youíre level increased. I havenít tried to level during combat but I think you can. Also itís easier to get perks and choose which ones you want. You get to pick a new perk every time you level, though you can save them and donít have to choose right away. So no longer to you have to level a skill to 25%, 50%, 75% and 100% to gain bonus in those areas. Note that most advanced perks have prerequisite perks so you canít just save all your perks and dump them into high level ones later. Also some perks have a minimum skill level requirement also.
Having logged way too many hours leveling in Oblivion this system is vastly superior, easier to use and more fun to play with. A huge improvement IMO.
P.S. Looks like David beat me to it.
