its probably best them sticking to what they know, if the devs are good at the arma engine, let them use that its still being developed so I wouldent be surprised if DayZ eventually ends up being on par with Arma 3, which does look very very nice :) in my opinion as long as its got that realism feel the horror atmosphere will remain

i tend to mute the ingame music and play the psx doom & doom 64 soundtrack, its ambient and suits the game very well, its pretty damn creepy its royalty free these days as well I think http://www.doom2.net/~doomdepot/music.html

always wanted to be able to ride a train through cherno or elektro :)

you could also have the opposite, cover your cloathes in zombie blood/guts so that zombies are less likely to see you ala "the walking dead" style you could perhaps an increased rate of catching a cold if you do this or the requirement to find a trenchcoat before doing it that you can dispose of later on

how about the ability to use your shotty/rifle as a crutch? reduce the characters speed and unable to use your weapon as your using it as a crutch a shot of morphine heals the leg like it does now always thought that a splint should be used as well as morphine, seems to make more sense would be abit brutal though having to find 2 things instead of just 1 thing to patch up your legs
