Well, you never sent a PM. So what I can tell you, is to keep playing and learn what each joint does. Pay attention to the ghost. The ghost won't be exact when fighting opponents. It can switch from showing you falling, to actually you tossing a guy over you. It has to do with the smallest joints that have such a huge effect. That's for Aikido.
For Judo. It's a luck game. Try to avoid dismemberments. If you can, grab hold and stay as far back as possible. It'll be a game of balance. Judo is the easiest Mod to get a hold of.
