So everyone would like to play a game

A Chess app aparently has had so many games played on that it can no longer store each game id uniquely as a 32 bit number.

Apparently youtube had similar problems but luckily they use factorials.
YouTube said in a post on Google+ at the end of 2014. “‘Gangnam Style’ has been viewed so many times we had to upgrade to a 64-bit integer (9,223,372,036,854,775,808)!”
