RDR was great and all but I wouldn't really want to play it again just in higher res. I'd prefer a sequel on PS4/XB1 since a) its not as if the game didn't sell well enough to warrant a sequel, and b) its been soo flippin long that a HD rehash would just be underwhelming.
I could never force myself to finish this game. I went pretty far but I never really loved it enough. I put it down one day and never picked it up again.
