Personally (i;m on PS4 btw), I'm looking at it as an opportunity to befriend more like-minded gamers so that when RDR2 does come out, we'll have a pool of players/friends that we can choose from. In a way, it can also be used as a tool to vet players for your particular group, playstyle, etc.
In my case, I'm just looking for older folks on PS4 like me who are just looking to have a good time and prefer to work with each other as a team (vs. just griefing players, etc.). We obviously don't know what the different play modes will consist of at this time so we'll have to see how all that plays out. I would just rather have a pool of folks I could tap into when the game releases rather than trying to brave the RDR2 online gameworld alone. ......and if GTAV:O is any indication of the potential for players to grief the weak and loaners, I would prefer to have buddies I can rely on.
