I thought the RDR Free Roam/Online was such a superior product to GTA5. I thought they didn't improve on it at all and even took steps back which is why I bailed on the game. But now I hear it's outstanding.
I used to play Poker and Liars Dice on RDR into the wee hours of the morning. To this day I think it's the best online Poker experience that a console offered.
