Maybe I'm dead wrong here, maybe I'm dead right. Here is my take on skyrim...
1)Alchemy... Why the HELL can't you make potions "on the fly" anymore like you could in oblivion? Now I have to GO SOMEWHERE just to make a potion? That's uber lame. Sometimes, all I needed in oblivion was ONE SINGLE water breathing potion to get through a certain part. And why did they feel the need to make alchemy idiot proof now? Was it really that hard to just LOOK at the effects and figure it out?
2)Aesthetic design... Okay, some of the aspects of the graphics are better, more detailed, but others, wtf? Character faces and expressions are better and more realistic in Skyrim, and the acting is better overall (although you have to admit the acting from the dark brotherhood members in oblivion was pretty bad-ass, like luciente luchante).
The water is better, and rivers actually "push" you down the river now.. thats cool.
Too much snowy mountains in skyrim, oblivion had more diversity in the geography, especially when you think about the shivering isles, that place was BEAUTIFUL! And that leads me to another point, the snow itself, especially when it's on rocks, looks way cleaner on oblivion, with more color diversity. In Skyrim, the snow looks almost like large sections of it are uniform in a particular shade of white, which to me looks cheap. In general, the colors in Skyrim are dull compared to the vibrant and beautiful colors of oblivion.
The detail at distances, specifically trees, looks sharper in oblivion.
3)Character customization....I prefer oblivion's system because you could create a character, and once you finished the sewers (tutorial), you had already put your character in the direction you intended to play it. It meant more careful planning, and it also meant that the first 3 characters I created were crap because I had no idea what I was doing. But, you know, that's how it should be. RPG's shouldn't be easy to play, or figure out, and they need to give you a sense of accomplishment when you figured out how to do it the RIGHT way.
4)Map.... I like that they at least tried with a 3D map, but it was implemented poorly. I can hardly see anything with all those damn clouds in the way, and sometimes the 3D map where there are large mountain cliffs it can obstruct your vision of other places. The 2D map of oblivion was simpler and straight forward.
5)hotkeys...FUCK being forced to pause the damn game just to switch weapons or spells. In oblivion you just hit a direction on the d-pad that you set yourself and TADA!!!
6)Critical hit animations..... This is the ultimate WTF for me. Critical hit? Sure it's a great idea, as a game mechanic, but as a "freeze-time animation" that can last like 8 seconds if your fighting a dragon, that crap gets real old real fast, I'm tellin' you.
7)Blood....Too much of it in Skyrim. It's too distracting and it does nothing for the game play. I don't wanna see a third of my screen being taken up by blood splatter every time I swing something at an enemy.
8)Spells... Say goodbye to custom created spells that you loved in oblivion, cas' they ain't comin' back.
What can I say, I hate Skyrim. There, I said it.
