Yeah, that's sadly true—shame you can't do the missions without the map/hud, some sort of paper trail would have been much more atmospheric... In general, I'd have liked to have seen a bit more balance between the character-driven—but extremely controlled—missions and the free roaming. I replay a lot (still my overall fave game), but mostly just free roam. For me, switching off the HUD really opened things up, slowed me down, made me aware of sounds, etc.
