1.kaos - the only scheme that requires a high level of creative thinking, unlike skill-based schemes in which the more you play the better you are, you have to be very creative to enjoy the scheme and become competitive
no other scheme has so many tactical options
you'll say, intermediate also, but it's much less flexible tactically and has a smaller amount of possibilites, something like a demo version of kaos
elite? bullshit for nerds, simillar to chess where you have to learn posible combinations, sometimes you may came up with something creative, but most of the time its just same shit happening over and over again, so unlike kaos, any nerd can be good at elite
