I remember playing it once with my jrotc buddies freshman year of high school...
...I had drawn up this badass Ork character, and the scenario was something like, a bunch of dwarves were fucking with us at a pub, so, trying to get into the swing of things, I decided not to take shit and fight these non-existing dwarves, plunging our team into battle....
...long story short, I got killed by something that only came up to my knees, and it left a bad taste in my mouth...
After that, another friend tried to get me into some modern-day zombie survival "Call of Cthulu" variant...and that was fun for a bit, but I never got hardcore into that thing again.
I'd give it another shot if I were asked to, though....I have more fun drawing out my characters than anything.
