If you really love me Kage then you will look for invisible HUD on Sphereii's Mod Launcher and record a session trying it out--for me. As much as you guys who love your HUD elements like to theorize about how awful the game would be without them, once you are forced to use environmental clues and pay attention to time and direction yourself, it is like a whole new game. A really really really new good extremely cinematic game. Please go give it a try! (And F7 is garbage compared to the invisible HUD mod. You need the mod so you have full functionality while the HUD is gone. Anyone who thinks they've tried invisible HUD by pressing F7 is fooling themselves.)
If they reversed my idea I would be happy to spend my hard earned skill points on that even though it would make zero sense thematically....lol
