Champions is a role-playing game published by Hero Games designed to simulate and function in a four-color superhero comic book world. It was originally created by George MacDonald and Steve Peterson in collaboration with Rob Bell, Bruce Harlick and Ray Greer.
More than two people were involved in the creation of Champions.
It's definitely correct because more than two people are mentioned in the final sentence. It's difficult because the system has trouble comparing numbers when more than/less than is used it seems.
