The National Collegiate Athletic Association (NCAA) will not renew its contract with gaming company Electronic Arts Inc., marking the end of the popular “NCAA Football” video game series.

The games have sold millions of copies since their 1997 inception, but have also led to some long-running litigation with former college football and basketball players who claim that the NCAA used their names and likenesses without paying them.

“We are confident in our legal position regarding the use of our trademarks in video games,” the NCAA said in a statement. “But given the current business climate and costs of litigation, we determined participating in this game is not in the best interests of the NCAA.”
