And one I heartily agree with.
Of course, I'm angling for the hardcore, "2020" mode in-game, with all sorts of PnP crunchiness like weight, endurance, blood loss, no automatic reload, one-save-game-only, ( that you can use wherever), critical damage rules, maybe even Permdeath. Although Permdeath is so subject to AI, fps-drop and other non-PnP issues, I'd probably just make it a switch.
Mind you, I'd also like to see an actual duration "sprint" - none of this 6 second crap you see in games or whatever. Have it related to Body and be 6 seconds per point in Body.
