@OP: I just started playing AC4. And let me tell you, I like your style ! I use to do the same occasionally, but it was just chance that I turned off all the HUD (well, I have ISS turned on).. I turn off the in RPGs specifically. Like Fallout 3/NV or The Last of Us, it really adds a new layer of gameplay: immersion.

@: everyone who have doubts about the subjekt discussed in this thread: take this as a challenge. Sit down one evening with black flag without any of the HUD turned on and see how far you get without it. You might thank us for it later!
