Game passes are items users can buy directly from a game's page. Game passes are similar to VIP shirts, but,
Game Passes that can be purchased (mainly in ROBUX)
because they are linked to the game's page itself, the risks of VIP scamming are minimized.
History
Game passes were added in September of 2012. Shortly after its release, ROBLOX's blog was made to give users information on them.
Details
Unlike VIP shirts, game passes allow users (even those without BC) to receive exclusive game features without requiring that the user wears that specific item. In addition, as an anti-fraud measure, revenue generated from game passes is temporarily witheld from the creator. Making a game pass used to require a 100 ROBUX fee. Later, the fee was waved and creating a game pass is now free.
