Blah, I'd rather have a game where you can "pull" or "drag" the limbs with the mouse, rather than have to click on each little joint and figure out where to contract or relax. Even though I could probably figure this out... I am not wasting my time, it gets kind of annoying after a while.
And playing online is kind of sad... I suppose this game is popular now for CS kiddies, because all I see is swearing and racist remarks left and right, and that is just not the game I want to be around.... and Singleplayer is boring if you are fighting a "dummy" model.
I watched your replay and i can only say that..you happen to play against pros too much? well that multi-leg-kick was pretty cool move from that other player, but about this replay i cant very much say anything, which would help you. He just blasted you but i could try to give you tip to go judo servers where disemberment is OFF. For example Judo Asia 2 (if i remember correct) , so there you can fight without your joints coming off, so its easier to learn. I remember that i only played in those judo servers where disemberment was off so i learned pretty fast there. I cant imagine that i could be new to game and go to some DISEMBERMENT ON server. I would be same frustrated as you, i think. So, if you see any players in Judo servers and where disemberment is off, go there, and im sure you learn more quickly there.
I really need to have a try at this, because it sounds weird I got on well with Rag Doll Kung Fu as long as I wasn't trying to actually do anything, so with a little practice I could do this.
