Other sports have been Olympic sports in the past (like tug of war). With the current position of the IOC to limit the volume of participants in the Olympic Games to 10,500 participants, it is unlikely that many of the World Games sports will be elevated to Olympic sports.
Some of the sports that are currently held at the World Games are acrobatic gymnastics, ultimate, orienteering, body building, powerlifting, finswimming, squash, netball, water skiing, and casting. The sports that are included in the World Games are limited by the facilities available in the host city; no new facilities may be constructed for the games. Up to now between 25 and 35 sports were included in the programme of The World Games. The IWGA, in coordination with the host city, can invite some sport to participate in the "invitational" programme. No World Games medals are awarded to invitational sports.
