I was reading the opposite of this topic in the Morrowind section, and actually I didn't like morrowind all that much compared to Oblivion, sure there was the customization
but my biggest thing with MW was that my sword almost never hit the enemy when I was standing right infront of them.
Well... first, that's only in the beginning of the game, when your character svcks at combat. He misses all the time because he.... svcks at combat. That was actually one of the things I preferred about Morrowind. Yes - the lack of animations that demonstrated just how my character svcked at combat was disconcerting - it would've been much better if there had been animations for opponents dodging, or the sword glancing off of them, or my character tripping over his own feet, or any of a number of other things that would communicate, "Hey - you svck at combat." But I liked that my character started out svcking at combat, because that made the progression in skill that much more vivid. Contrast that with Oblvion, where my character's Zorro the instant he picks up a sword. He might never have held one in his entire life, but bang - he picks one up and he's instantly the master of the blade. I found that extremely dull.
The things I prefer about Oblivion:
It's less challenging. Actually - that's not a thing that I prefer overall - it's just a thing that I prefer when I'm in the mood for something less challenging. It means that when I get the urge to just turn the game on for a bit and throw together.... oh.... say an Altmer heavy armor tank under the sign of the Lady, I can just switch the game on, throw the character together, swim across to Vilverin (or hike over to Sideways Cave, or travel all the way to Fort Coldcorn, or go absolutely anywhere else on the entire map) and clean the place out, without hardly breaking a sweat. Morrowind, on the other hand, requires an investment - I have to be much more conscious of character build and have to be careful about where I go and what I try to do, since the world isn't pegged to my character's level. And because low level characters pretty much svck, as they should. But, when I'm looking for a challenge, I prefer that.
I much prefer archery in Oblivion, for a few simple reasons. First - the arrows actually follow an arc in flight rather than a straight line. Second - collision is much better defined in Oblivion - for the most part, if you can see through it, you can shoot through it, and the bounding boxes for things like doors actually line up fairly well with the meshes. And third, you can retrieve arrows.
I sort of prefer the feel of Oblivion, but that's more a mood thing than an absolute. Vvardenfell is, in many ways, a harsh and lonely place. Wandering around Molag Amur is sort of depressing, just because it's so bleak and forbidding and empty. Cyrodiil, on the other hand, is a cozy and inviting place. Yes - it runs a bit too much toward over-manicured golf course for my tastes, but there is something to be said for running around with grass under your feet instead of volcanic ash.
I prefer the variety of NPCs in Oblivion, though I miss the depth of Morrowind. I could sit all day and list the characters who stand out to me for one reason or another in Oblivion - everyone from Falanu Hlaalu to Lord Rugdumph to City-Swimmer to.... There aren't as many characters in Morrowind who are that well developed. But there aren't really any characters in Oblvion (and yes - I'm definitely including Martin and Jauffre and Mankar Camoran and so on) who are as intriguing and unique as Divayth Fyr or Yagrum Bagarn or Crassius Curio.
I prefer sneak in Oblivion, but about all that can be said about that is that it was less bad.
I sort of prefer the range of face customization possible in Oblivion, but just as much, I wish the races hadn't all been hammered into bland sameness.
I prefer the power attacks in Oblivion, just because there are more of them, and with decent animations (in third person, at least).
And...... I can't think of anything else.
Oh yeah - and this.
