The biggest difference for me when it comes to making a new character is that Skyrim allows me to create a more unique character at higher levels then oblivion did, while Oblivion allowed me to make a more unique character in the early levels. My problem with oblivion was that once I had built my character up I kept training all the other skills for the extra levels and for [censored]'n'giggles. The problem was no matter what my starter class was I always ended up as a Jack of all trades, I could sneak around being a assassin and in the next second pop up and rain fire and ice on the enemies in front of me. Don a heavy armor and start charging into battle like I was immortal. And my starter class was assassin... Of course I could have limited myself by not allowing myself to level up the other things, but I did it because why should I make a new character when I could simply just become master of all skills? Skyrim I do like better in that aspects as I can create an assassin that is a lot more specialized in being a thief and assassin, my next playthrough I can make a warriormage that uses heavy armor a swordand spells. Both of them starts similar, but the more I play them the more different they become in playstyle.
The removal of classes and stats is a change I like. I like better when I can play what I want rather then play a preset and in previous games I always pent a lot of time thinking I need to train that skill this much, this skill that much to get the best result to place on stats. It automaticly made me min/max my playstyle simply because at higher levels if I gimped myself by not doing this I could break the game in the ways where I was good at only one thing and useless in any other situation. I had it happen on 2 playthroughs in Oblivion and it annoyed the crap out of me, so the third character I started planning ahead and spending a lot of time planning my character. And when I got to the same point as I was previous I was a much better character in sevaral situations. In Skyrim I was skeptical at first when I heard and saw no stats and no classes, but when starting to play it I was won over to the dark side. The game felt natural, it was more me playing my character and enjoying it then me planning my character ahead making sure I trained the things I knew I would need. I'm on my 4. character now 2 of the previous was also assassins testing different builds, and one was barbarian type. And at level 47 I still find myself enjoying my character, doing dungeon crawling, looking for new places, talking to people and reading books in hope of hints and clues to things I can look into. There are things that they can do to improve the game, but the way the character building is I can easy see myself make a second character at some point that is totally on the other side of my stealthy assassin. A big bad warriormage with heavy armor, weapons and that in general cares little about going about the world unnoticed. Even if he gets 100 in sneak he will be a lousy sneaker compared to my assassin due to perks. And that is what gives me the replayability.
