i thinkt he game will be great just as long as we have an improved melee system maybe (I say maybe, as i'm not sure how it would work and i don't know if it would be a good idea or not) something to do with online play, weapon models for special weapons that are *NOT* the exact same as normal weapons (AKA i don't wanna see an uber legendary awesome weapon that uses the exact same model as a glass longsword.
horse combat this time around i think would be rather essential, i often found myself having to get off the horse just to stop myself from dieing from arrows or a raging bandit lunatic in Oblivion.
a better lighting system, to me, Oblivion and Morrowind were always to bright or to dark, i couldn't stand constantly having to change the brightness whenever i entered and/or left a dungeon/cave/whatever.
add more to the thieving side of the game, stealing was way to easy in oblivion.
finally, fighting stances and such, i never used two-handed weapons in morrowind nor oblivion for a simple reason. the fighting with them sucked. the character looked like he was trying to play baseball, not combat the forces of evil/good.
also, since the game is set in skyrim, i wonder how, or if, they're going to incorporate the usage of other races besides nords into it. from what i read of the storyline it seems to me you'd be forced to choose a nord for the game to make any sense at all, anyone know anything about this?
