Judo takes a lot more prediction and planning rather than, for say, aikido, where you make small steps every frame. In a way, judo takes way more effort and skill than most other mods. I think people don't believe judo requires much skill and does require a lot of luck is because of how fast paced it is. I disagree with that. When I didn't know how to play judo, that's how it seemed, but I started thinking about my next turns and began to start using 100% of my skill. If you play it for awhile, you'll most likely, eventually feel the same way.
