How do you set up a custom game that is open to people BESIDES friends and clan members? I just tried for a half hour to set up a game of Rumble Rockets but only people from my friends list could join. I just want to set up a match so that people using Quickmatch or Optimatch can join my game. Can this be done? I know this sounds like a stupid question but it seems like I tried everything possible and still no luck.
