Yeah, Dos is an acquired taste, you better try Dos2 first or use the Epic encounters mod. =P
I think Larian always does a fine job in making interesting and interactable maps to explore, they just needed a solid ruleset to back up and balance the combat and character creation, and I hope they found it in the alliance with WOTC.
Until now they seem to be keen on following most of the guidelines of D&D5e, with some adaptations to a different media: a videogame; so I have high hopes with this game.
I will reserve my opinion about the story, dialogues and characters until we have more information, but right now the plot seems unusually interesting.
