What do you think? I thought maybe it could lower your stamina like you slow down after running a certian amount of time and it gets progissively more harmful to a certian stat that involves speed. And maybe in exchange it can make your accuracy increase in VATS or give you a steadier aim shooting something down your sights. Or something to do with increasing your focus?
also thought a smoking gun would be cool after you unload an entire magazine on something. Or was that already in Fallout 3? Maybe more visible smoke coming off your guns then?
