This isn't even to mention that the creation of RDR2 caused a rather noticeable problem, and plothole with the original plot of RDR1-the remaining new gang members.
In RDR1, the plot is that you're forced to hunt down and kill/capture the remaining gang members which in the original were just Bill, Javier, and Dutch. But RDR2 has thrown in five extra members still on the loose.
Now to be fair, only Charles was added to list of remaining members that the cops know, but Charles is now in Canada. This means that A) they either need to add a whole new region in as well as new missions so you can go get him, B) write, record, and code in dialogue so it says he was gotten by the authorities off-screen, or C) ignore it, and make RDR2's relationship with the original RDR feel like even more of a pointless clusterfuck.
