I don't like GTA games, should I buy Red Dead Redemption 2?

Just get the first game and give it a play through. You can pick it up cheap these days. It might even be on Gamepass at the moment.

I only have a PS4 and didn't find any RDR remake in shops and in the PS Store. What is a Gamepass? Can I use it in Europe/The Netherlands?
