Yeah, last time I played it was the PS4 rerelease, so almost 8 years ago, and playing it again now almost feels fresh despite having an overall idea of where the plot is going. It still holds up ridiculously well against other open world games.
While I think RDR2 is probably the better open world in terms of detail, this has just a more fun tongue-in-cheek attitude that can keep a smile plastered to my face in a way RDR2 just can't since it's considerably more straight faced in terms of it's characters and plot (not that that's bad, it's just takes a different tone and is more 'drama' than 'fun')
