IMO, white wolf games suck pretty badly, too.
I've been playing Vampire/World of Darkness a few months last year. It sucked even with a pretty good GM.
Just so unrealistic...
The game I showed you above use the d100 system. That's two dices with 10 sides, one marked with 0-9, and the other 00-90 using double numbers (00, 10, 20, 30, 40 etc).
So, say that you have a skill in your martial art, or just the generic skill "swords" with a value of 15. The normal chance you have to hit is with three d6:es, and you are supposed to get under 15 with that.
If you hit a six, you have to pick up that dice again and add another dice and re-roll, making it harder to succeed.
Anyway let's say you hit the guy (normally high, middle or low but there are also tables for specific areas like head, torso and whatnot)...
Anyway, when you hit the guy, you roll the d100 dices and if you get, say, 65, you hit the chest.
Then you roll your damage with (most often like 5 d6:es or such), and if that value goes over 20, you roll a d10 to see what critical damage you get. Like fracture, severed artery, spine, brain, heart or whatever... The criticals are different depending on where you hit of course).
The entire game is like that, so the fights are really time-consuming, meaning that you usually only fight a little bit. The rest of the game is social.
That's how I LOVE it.
