If only your arguments were sound as well.
There's no way to examine why one game sells better than another? That "argument" is just as general and vague as the ones you are trying to help. Ofcourse it can be done, it may be speculation or more objective in terms of quality or target audience, but it can be done on game boards or by the companies themselves. What kinds industry would it be if this basic analysis isn't done? I'm not sure you're in a capacity to speak for the entire game industry which is the root of the issue...a general, blanket statement like that has zero merit. It's your opinion with little basis provided.
Secondly, your comparison is irrelevant. We are talking about comparing two video games, not an absolute like the impossibility of flying to the moon in a balloon. A more apt comparison would be, comparing why two products, say vacuum cleaners, sold differently. Was it price, quality, or marketing differences? Those are potential reasons.
And in the spirit of debate, I'll give you one of the reasons why Divinity sold better - Co Op. The macro trend of the industry is more multiplayer, more ways to enjoy games with others. Also, being heralded as one of the best RPGs ever is another. Sure Deadfire won awards but I have not seen the same level of media attention that Divinity 2 got. So there are some reasons worthy of discussion.
