Please write a summary of what is a polearm and its history in a nutshell. I wish to use this on my web site. Please expand the summary with a blog of where polearms are found and used in today's world. Such as video games, online competitive role playing games, live action role playing games, and of course martial arts. Please provide examples of names of those games and the types of martial arts that use polearms and explain how a polearm is used in those games and arts. Close the blog by relating that Polearmball uses a special polearm designed for the game. (In Polearmball the polearm is used as both a projectile and a jousting pole. In this version of polearmball jousting is not equestrian and is done on-foot.)Polearmball is a role-playing coed team sport.
