I would like to come back to the third map idea, like you can hit a button and it switches you from what you can clearly see around you to what you can remember things looking like, purely because sometimes, at least once, i think everyone is going to walk into some placey-place and think it’s all cool, and then just get slammed by monsters they didn’t know where there. Mainly around your main base too, since that’s probably the only place where that’s going to happen, which is going to get very annoying.
Also, I think that ourselves as the player should just remember it ourselves, I mean a lot of the houses are kinda predictable, and most buildings just feel very copy and paste and you always have an idea of what to expect in terms of the shapes and sizes of rooms and walls. So, it could be argued that not having this as a feature adds to the immersion of the game, something kinda irrelevant, but very nice, to put the responsibility on the real life player.
I will support this, only if it is a separate map you would use whenever you just temporarily forget and kinda need to remember the rooms nearby, not the same as the dwarf fortress one.
