Oh, how happy I am to see a fellow fan! I can't even count how many times I've played through it—it's the best western ever. I absolutely love its music; for a while, I listened to it nonstop... Though Call of Juarez is just as great—I mean, Ray's charisma really makes it special.
RDR 2 is, of course, an excellent western as well, but there's something unforgettable about these older projects that keeps drawing me back to them again and again.
Sorry for the stream of thoughts! :D
