Hi Al,
I don't know something about an event in Rosenheim called World Games.
I think it is critical to use this name without any permission.
Here is the history of the World Games:
"In 1980 a group of 12 International Sports Federations decided to join forces by forming the World Games Council, later to be renamed the International World Games Association (IWGA). The founding meeting was chaired by IOC Executive Board Member Dr. Un Youg Kim, who is also the President of the International Taekwondo Federation. The purpose of the new organization was to create a multisport event for sports (and/or disciplines of sports) not included in the programme of the Olympic Games. This aimed at, among other things, creating more exposure in the media and increased interest from spectators, which would assist the Federations in developing their sports. This initiative came during an era when international sports, including the Olympic Games, were yet to become the great television success - and thus the sponsoring venture - they are today."
