Dungeons are annoying and troublesome to design, hallways don't work as well in 3d enviroments as in 2d, neither do they feel as good to traverse, takes time to code and to be fair a "building with 5 floors leading to the final boss" was getting kinda reptitive.
GF just don't wanna spend the time or money to make interesting game enviroments anymore when they can just put in 25% of the effort and sell one trillion copies. They've also allocated their resources to a lot of other things like characters and "story" (shitty and drawn out stories) these days.
They would rather make a game that sells well than make a good game.
