I'm rather confused as to what you are trying to say. I guess that I'm a mainstream gamer, but I've played indie games before and loved them. I didn't really like Oblivion that much because of the enemies leveling with you (as I said, I like progression), but the combat system was decent.
I really wanted to know how much DKS addressed the issues that faced the original. I'm strongly leaning towards buying it, but I can't find any good reviews for it that address the gameplay changes.
I just mainly meant polish and ease of use versus depth. Oblivion appealed to a larger base of people because it was slick and simple, compared to other open-world RPGs before it. If you like RPGs without needing them to be like that though I think Divinity 2 is an under-appreciated and great game in the genre, especially the PC version.
