>>14752233<---This is my first postNow, myself, I don't need the rules really, but having a list of equipment available and skills and traits of some sort is nice, it makes the players feel they can flesh themselves out, and the feel of these things are the easiest way to tie them into the setting. Just the naming of stuff in the serenity RPG is pretty damned good, and sets the overall feel nicely.
I don't really need the combat system, I usually disregard it a lot no matter what system I play, sure, I make the players feel that they are using a system, and I scratch bad guys according to their whooping damage rolls, but when I start dishing out the pain, I mostly just go: "He kicks you in the nuts, you probably remember what that feels like from kindergarten, you keel over, and just as you look up, the boot hits your face." Of course there is a roll before this, fake, or some times, real.
If the players break the system, I don't really care, I can just be nastier than them anyway.
