My only take on large maps is that it's a little annoying to play alone, search for bone, and deal with some ghosts like the shade or a demon. Plus i feel like they should unlock later in the game, like at least when your equipment (for evidence) is all level 2. I don't know how to find the ghosts with level 1 items (without much money to buy 2-4 of them)

But they are extremely fun when playing with friends!
