I wish they'd put something like Raven Rock in Oblivion. I'd even settle for a third-party mod.
There is:

Great mod.
OT:
Horse combat.
Better overall combat (like Fallout 3 would be acceptable).
Better stealth (anyone who's done the thieves guild quests without Illusion or invisiblity potions in Oblivion will know what I mean).
Shitloads of small, menial tasks (eg-deliver some bread to some random feller because he's hungry).
Reactive npc's ('You saved me town from a fuckload of demons, have this free pie!' as opposed to 'Yeah yeah whatever you want this pie? 50 bucks.')
Having singular pauldrons gauntlets etc (coz mixing and matching is fun as it is awesome looking).
MORE PEOPLE. I cannot express this more. Oblivion totally fucked the concept over by having about 13 people in each city. Screw original names, just do what they did in the Fallout series. eg: 13 interesting quest givers/ important/semi-important npcs with actual names and a fuckload of Peasant, Guard, Guy-Who-Sits-Around-On-The-Park-Bench-And-Eats-All-The-Cheese-Rolls-From-The-Bucket-Of-Cheese-Rolls-That-You-Were-Going-To-Sell kind of npcs.
More small villages/towns/farmhouses. Morrowind did a great job of having about 6 major cities and like 30+ random little villages and farms. Adds huge amounts of realism. Oblivion mucked it up by having 8 or so major cities and about 3 villages/farms.
Varied landscapes and terrains. See Morrowind.
Non-Physchic guards.
More quests. Actually kinda repeating myself here but I'd like to see the kind of thing that the guy from the book store tells you to deliver a letter and if you do so without reading, quest done. However, upon reading it drags you into a huge questline of betrayal, murder, thievery, all that kind of bullshit that everyone(yes even you) loves.
Different quest endings/options. Goes hand-in-hand with last paragraph. And I don't mean the generic bullshit Good/Evil/Neutral stuff (although that works too) and more of the I've-Just-Murdered-Mr-Henkie-From-Down-The-Road-Should-I-Turn-Myself-In-Or-Hide-The-Body kinda thing. Actually both of those are good alone, together they awesome. Oh, and also that if you make a single different response it won't go all to the same ending. Eg: Heres a quest, click here for Good character, Here for Evil, and Here for the guy who doesn't Give A Toss Either Way, then procede to generic same quest end.
Make fast travelling only available through Cities/Villages/Towns etc etc and not every single little cave and ruin. That or go back to the whole siltstrider/boat/magey teleporty thing.
Make the major military faction actually BIGGER than the generic evil bandit/maurader(yes I know thats spelt wrong, F-off)/hiwayman factions, because I was so sick of having EVERY FUCKING SINGLE Imperial Fort in ruins and controlled by outlaws and evil-doers in Oblivion. I mean, what happend to fucking military pride? And also, isn't Cyrodiil supposed to be the capital of the Empire? Shouldn't it have more security than nowadays airports? And what happened to this so called Imperial Legion? Are they all on fucking holidays in Hammerfell? And Oh Dear this seems to have been turned into a rant. Sorry.
Thats all I can think of for now, I'll probly think of something JUST after post this but meh.
Edit: Shit I just remembered, right on time AFTER the post btw, BETTER VOICE ACTORS. AND MORE OF THEM. Yahtzee explains better so just watch his review on Oblivion.
Edit Edit: Wow what a fucking great whopper of a post.
