I think we can all agree that an always-on minimap is bad. Like the TV in a bar, you find your eyes drawn to it even when there are other things you should be looking at. You stare at a corner of your monitor while ignoring the fancy grandeur of whatever expensive open world is taking up the other seven-eighths of your screen.
But the absence of navigational aids can be just as bad. I got lost more than once in Clair Obscur: Expedition 33 in areas where there was no map at all, and just had to loop around the place trying to find the one bit I was supposed to go to next. And in an FPS, you may not need to worry as much about getting lost, but you will need to worry about losing enemies when they duck behind cover.
