Chaos League is a great game, very difficuly, but very rewarding. A real gem.
You assemble your team, and you see what they can do. It has a rather difficult learning curve, but once you get into it, score you first goal it all becomes crystal clear. It is addictive fun! Carrying your players over, and seeing them grow with all the experience, and then having them die, when you do not expect it.
The matches are 10 minutes long, which gives you just enough time, not too long and not too short. The varied races ,spells and styles of play really gives it replay value as well. So if you do happen to stumble upon it, get it!
