Movement speed, Definitely. I HATE walking from one end of Freeside to another because it looks like it will only take a minute or so but it takes about three.
Jump height, HELL NO! I hate the fact that if your athletics is high enough in Oblivion it gives you the ability to jump like a frog that abuses steroids. It's insanity.
its not insanity! its pure fun! someone never played deus ex.....

my thread on perfecting skyrims gameplay
my other thought on the game as a whole, taken from another post-
it has happened, i have got bored of skyrim. probably about 40hrs gametime (works out to £1 per hour, good deal) 105 locations discovered, 61 dungeons cleared. couldnt take it no more. dungeons are still too similar. if i had to fireball spam my way through one more army of those draugh zombies id have fallen asleep. game is just too big! too big to have NPCs react realisticly to player actions, too big to not use the same voice actors repeatedly, too big to have branching and interesting quests, too big! its even worse when the gameplay has gotten considerably more simple since morrowind. but im mad at myself for not just getting on with it since the game is a wonder to behold, and beautiful to look at. and just thinking about all that hard work developing... i guess im just spoiled by the better games in the genre like deus ex and arx.
to say arx is better than skyrim might seem like blasphemy from a developers perspective, but for me arx holds my attention to the very end, i want to explore every nook, story is primary i wanna know what happens next, there's considerably less dungeons so they have more time spent on them. a level system that doesn't encourage power levelling.
but theres more to it than that.
in arx you go into a dungeon sh!tting it not knowing what to expect. in skyrim its the same experience for each theme of dungeon, with a few exceptions.
if skyrim was the same size as fallout NV i think it would be a much better game, i dunno maybe im wrong.
highlights of skyrim- those amazing waterfalls (couldnt name the area) the dragons and the shouts, especially whirlwind sprint. well the world map in general is just fantastic and varied. just a shame most of the locations are a little dull. and why is the interior to every pub/inn exactly the same. what a shame.
so less is more is certainly applicable here for elder scrolls in all but gameplay features.
