its been a while since ive played it so i cant go into any detail about the skill system, or enchanting, or alchemy or anything like that, but to me, fact is, marrowind is so much more engaging then oblivion and skyrim. skyrim is not a bad game, but i dont think it deserves game of the year, because for all of its "free-roam" (quotations because i feel it isnt exactly free-roam, because you are in essence locked into questing, because you cant find items, or kill bandits without later finding a quest for it that you now cant do, becuase you already did it before you got the quest, so now its broken), and also because its too streamlined, and linear. the game as a whole feels very narrow-minded. i dont think it does a very good job in grabbing my feelings torwards its story line, (except the child in windhelm who was an orphan, where you start the dark brotherhood quests that i just did), or really trying to feel a sense of "kinship" torwards its sruggles of the civil war. i can create my own feeling of how their telling the story, but actually writing the feeling, actually trying to create the atmosphere that it is a land split, and people are torn apart from eachother, i dont think its very engaging.
skyrim in gameplay, i think is alot smoother, and things are easier to grasp, but if they took the systems of marrowind, left all the spells of each school of magic, and applied them to skyrim in the way skyrim is designed, i think it would make skyrim alot better. if there was something else, something more besides a "civil war", something close to the slavery of the khajit, (something id ont have to create on my own, or pretend it exists through RP). skyrim just feels lacking in some areas, where there should be a little more substance, a little more feeling, and a little more "presence".
skyrim is just missing something.
