You disgust me.
Mate, that had me laughing so much, my flatmates think I've gone off my rocker
Dave, this Dave-sim sounds a bit (not completely) like what we do at Tim's farm - only on a larger scale, and without the all the 'safety breaks' we have (if a certain someone wasn't around I'm pretty sure we could do it too). Also reminds me of this:
I could last about 3 days max, so long as I was given some breaks (about half an hour). It depends on what I'm using and how hard the games are - since I've started using my LSW-carbine rather than my LSW, I've found I can last a lot longer.
As I haven't done a proper milsim in a longtime, I can't say about that.
I've done a day-night-day-night-day fight before. Was completely knackered afterwards, but that may have had more to do with the fact that I entered the event with a hangover caused by a night clubbing, drinking far too much and 2 hours sleep, and I got about 10 hours sleep throughout the entire event... I seem to recall sleeping for nearly 2 days straight afterwards...
