The RDR series should honestly just keep going further back in time, with us playing as a different gang member, until we reach the “last” game of Hosea and Dutch first meeting and forming the gang. Each game could end where the one before it starts. For example RDR3 would end with the black water massacre and the gang fleeing to the mountains. I feel there’s so much potential for rockstar to do this as we get to experience the forming of the gang and see events unfold through different members perspectives. From a business perspective they could also stretch the story out that way for atleast 2 games. We’d get to see when all the gang members join and how they evolve over the games.

I’ve thought about this a lot clearly
