RDR still looks great, theres not really a reason not to play it. And Undead nightmare is a great expansion
I think its a bit overrated tho, writing's inconsistent as hell and the gameplay's pretty shallow
best shooting in a sandbox rockstar game still. Like someone said the sound design is top notch. Its hard not to enjoy it. Doubt the online's still active and that was a major selling point to me.
Wild West is a really underused setting in games, RDR 2 would be great just to have another cowboy game.
