I can understand
And I'm very pleased you love DD very much and hope you've still hours and hours of game pleasure !!
I love both games, but for different reasons !
Some of them ?
For the story (+ with the seven races) & music I prefer DD mostly .
For the Skills, combat (thanks to the lovely Priest skills!!) and trading I mostly prefer DKS
(but trading in DD is of course also big fun, but for some personal reasons I like more the DKS shopkeepers)
Quests in a RPG I always love them (except if they are all of the same type, I like variation)
