Okay, slight exagerration, but in games where you are navigating your little avatar through the game world, a game world map is a negative to the experience. The reason is that you end up looking at your little arrow on the map instead of looking at the game world. This is especially jarring in medieval fantasy settings since GPS definitely does not exist within the fantasy universe. Dragon Age 2, I'm looking at you. And worse, you can't disable it in the game settings.
