I honestly believe a HUD minimap is one of the worst game UI elements a game can have. There is rarely a canonical explanation to begin with as to why your character magically knows the layout of rooms they haven’t entered and even worse that they know the position of enemies.
I agree. I like the way old-school rogue-likes would handle it (where you’re an @ symbol). You wouldn’t see anything you haven’t seen, but your map would remember where you have been and what things looked like at the time you last saw it (more or less). I’d personally just rather have a compass than a minimap, that way it could tell me which way I was facing and I’d have to rely on environmental cues for the rest. Maybe footprints if you have walked by there lately (or something has).
