You might want to check out this one-on-one-on-one comparison of features in Oblivion, Morrowind, and Skyrim. It makes a great deal clear. If you're running from a PC, you should be able to install mods, and some are pretty important: the Morrowind Code Patch both deals with corruption issues affecting adding and removing mods, as well as quite a few fixes, and adds a lot of user configuration choices. Also, the Unofficial Morrowind Patch fixes a ton of bugs that got past Bethsoft. Finally, the big deal about combat is that Oblivion and Skyrim are FPS-like in that you can't miss in combat, and neither can your opponent. Morrowind uses a D&D-flavored die roll, based on a few factors, of which the most important is Agility/Dexterity. So if you have a a high skill in a given weapon by low agility, you'll be like the person who intellectually knows what to do with a sword, but never swung it. Best of luck. It's a great game. :)
