No one likes hyperbole. They need to commit to making Fallout 76 enjoyable because from what I have seen it's very bare bones and quite honestly boring.
RDR2 is a console game just like GTA6 would be. Diablo fans wanted Diablo 4 on PC and instead they got a Diablo game for mobile, if you don't see how that is disappointing then there is nothing else for me to say.
If they hope that RDR2 port on next gen consoles will sell millions of copies like GTAV did on PS4/X1 they will be very disappointed. RDR2 is not GTAV. RDR2 Online will not be as popular or have the lifespan of GTAV online. RDR2 is the popular thing now but it will die like any other game after a while. GTAV is a very special case.
