I've already moved past wanting RDR ported to the pc. I've beat it on the 360 and ps3 and there was a time I would have been all over a PC version as well. Now, just give a us a sequel. Don't waste efforts to bring a decade old game to modern hardware. That or Bully.
If 360 on the Xbox one is fairly painless, then do that but I rather see Rockstar work on something new.
