While I think the RPG tag is legit (stats management, roguelike elements with a good risk-reward system) I think this really plays more like a management simulation (a dark ages, plague-ridden, demon infested estate management simulation) or a strategy game.

Not to make light of the elder horror situation thing here, but going into the dungeons itself could be a kind of sport, especially in the way you manage teams and character classes, weighing disadvantages, risks, how much provisions to take, etc. Every session feels like you're actually mounting an expedition.
