For years, passionate fans have argued over whether Rockstar Games' flagship franchises exist within the same fictional universe. Now, a tiny detail involving dollar bills in a strip club scene in the second Grand Theft Auto 6 trailer seems to have provided the smoking gun many have been searching for - unless it is just an easter egg.

A blink-and-you'll-miss-it moment from the new trailer shows cash featuring President Thaddeus Waxman's distinctive face and frowning mustache. If that name sounds familiar, it should. Waxman was explicitly named as the president during the events of Red Dead Redemption 2, which takes place in 1899.

This connection establishes a direct timeline continuity that strongly suggests these beloved titles share the same fictional America. The presidential currency isn't isolated evidence, either. The new trailer also features weapons from the "Duke" gun brand. This fictional firearms manufacturer is prominently featured throughout the Red Dead series.

The fact that this brand has survived from the Wild West era into modern-day Vice City provides another thread connecting these seemingly separate worlds.

This isn't the first time fans have spotted a connection between these two universes. Grand Theft Auto V contained numerous nods to the Red Dead series, including bookshelves lined with novels by "J. Marston". Grand Theft Auto Online even allows players to select Marston as their character's father, further cementing the connection.
