I like DD for the story and the gameplay and the amazing character development options etc, it just so happens that the graphics are in a format that I have always loved, and have been done with so much love and care that for me, they shine.
I agree with you for all these things. I will add the sense of humour which is always present in DD and of course the music.
Everything is also well balanced, not too much quests, not too much fights.
I hope Riftrunner will be as good as Divinity.
Specifically about graphics, i am just afraid that the 3D low-polygons characters could be a little bit less beautiful than 2D characters.
while I might have reservations about 3D, I trust the devs to do what they think is best, and judging from DD, that "best" is pretty damn good.
I am confident in Larian too, they are doing the best to give us a great game.
I hope to see the demo of RR very soon !
