Is divinity original sin better than these two?
Gameplay in D:OS is better than those two but the writing and overall experience is fucking horrible. My 4 year old daughter could come up with a more engrossing story.
EDIT: I'll second others on the opinion of Underrail. It is going to be the best cRPG to come out in a long, long time. And this is based upon in depth experience with the EA. The finished version will be something that will be a New Golden Age unto itself. If you buy any cRPG today Underrail is the one you want but the only reason I didn't write that at first was because it wouldn't have answered the OP's question.
