I could only tell you what "next gen" rpg means to me, because when I play them, I wont care about the graphics or the animations, whatever.
What I like from that article... I copy paste
1) more sophisticated dialogue, editors, and this would result in more sophisticated depictions and dialogues with subtler camera work, with sounds helping tell the story rather than just be there in the background," writer Jakub Szamalek told me.
2)"We want to make it as alive as possible. And when the wind rolls - so you have a grass plain and you see the wind moving - you get this motion. It's much more alive. Before it was just animation." More AI characters can be spawned now and they will move and behave more believably. Balázs Török was impressed by the big and believable crowds in Hitman: Absolution. "You didn't see puppets just standing there," he said. "More games will do things like this."
3)"We have a full day-night cycle, as we had in The Witcher 2, and in The Witcher 1, and with this it's very important that the artists don't have to make different assets for night or even check the assets in different conditions. They just make one asset and it should behave properly in all lighting conditions and in all weather conditions, because we have a new weather system which is pretty cool."
I love dialogues and choices in dialogues, not only that, but to impact my overall gameplay experience, depends what choices I make. If a game is restrictive, whatever choice I make, Its one way road. So, I love next gen RPG's to pay allot of attention into lots of dialogues and lots of choices. Also I want the AI system to be clever and wide, if I have an enemy, with my choices I can make him my friend and vise versa, at any time... I need clever npc and choices even to correct some of my "past" mistakes.
I love it to be alive and I want it to make me explore it... if its a beautiful scenery and nothing else, or no motivation to explore... its a turn off.
As for the skyrim, its a great game, it has its own story but its very small, 5-10 quests all of it, but it gives you also dynamic quest system with numerous of quests to do and explore!
It would be great to have bigger story, but I also need and love the dynamic quest system for never ending missions and exploration. So a game with limited story, is not that great, but also a game with allot of story and limited side questing and exploration is equally bad.
And I love moding.
