PS3 Online question (randoms joining my game?)

Hello! Joined a friend’s game with an invite and randoms (non-friends) kept coming in and out of the game? Are there a settings (like TPS) to set network to one of – Friends/Public/Invite Only/Offline? Or – if you play online with a friend does it become a public match? Thanks for any info.

Haven’t you noticed? There’s two privacy options in the main menu. For friends only and public. You can’t change it in-game.
