Oh there's more than that.
But the combat system fails as an RPG-ish system as well, because it requires way too much player skill for that. Best example is ranged combat, where not only you have to roll high enough, you also need to hit the enemy physically, which is much harder when the enemy moves...
Dagerfall did it much better, but even that had problems...
Not really, while maybe it is a little exagerated, it's easy to hit someone if you put your "weapon-skill" on Major. Yeah, if you have "Axe 5" it's perfectly obvious why you can't hit s**t with that kind of weapon. The "problem" with Morrowind is that, when you create your character, you have to actually think about what you are doing. You can't pretend to have a Mage if you pump to the max only your melee and armor skills.
Oblivion did some good things, but really, whats with all the skills removed ( and with the poor content )? I maybe understand Axe merged with Blunt ( a bit ), but where the hell Short Blade and Long Blade are? I don't like my character being able to use a dagger in the same way he uses a long sword. There is technically nothing wrong with that, but you feel like using the same freaking weapon, just with different stats.
And this is just b***ing, don't get me started on the serious part, like how the world is in black and white morality. And speaking of black and white...
As for nonlinear quests and consequences, in Morrowind, quest non-linearity ended in "do something to this guy, or kill him" and killing that guy hardly had any later consequence.
Actually, it was more complicated than that. While
sometimes you still had to "do something to this guy, or kill him", you had more freedom about what to do with the whole thing. Also, if you join a faction and do missions for them, some of the other ones will start to hate you. Yes, even if you're a part of them. Isn't that a consequence?
I could even steal s**t from people and sell it wherever I want.
OH, looks like the RPG-ish game with omgugly combat system tried a more believable approach. OH! THE IRONY!
Play Morrowind and try some side quests, look how "gray" the morality is, and how many different shades of it there are. Look how deep the detail of the world is. It's not just quests, it's
everything. IT'S THE WHOLE THING AROUND YOU.
Oblivion is all OMG SHINY GOOD KNIGHTS OMG DARK EVIL BEASTS.
