I loved RDR1 and think 2 is better, gelled with it from the get-go. I guess it's just my type of experience as a fan of western stuff and immersive games. Turning it into GTA with horses would be the worst thing they could've done.
When I played it on the PS4 Pro it felt almost next gen in many regards.
It's different than 1. Slower and more deliberate, has a lot more dialogue, expands on many elements like hunting, interactions, stuff to do and the world is more varied. In fact it's the best looking and designed map I've seen in many years with AC Origins taking second place. Also, Arthur is a better protagonist than John.
I'm sure this game will be divisive as hell on PC but it absolutely deserves the scores, it's quite the achievement in many regards. If it runs decently on a 1070, I'll double-dip.
