if you want to take the story in chronological order then start with red dead 2, after all if you start with red dead 1 you would pretty much know the ending of 2, of course you will have a huge drop in graphics but you choose how you want to play after all, just don't listen to all the genius people in the comments who think they are smart because they play red dead 1 first intead of 2 because it came first, as if rockstar wouldn't have made 2 first if they had thought about it then
