Question: will rdr1 come to pc?
Answer: It doesn't have a PC version but there is a mostly working emulator version of it now. You can see it for yourself here. RDR1 isn't on PS4 is it? If you have a powerful enough CPU you can emulate the game on the PS3 emulator RPCS3 or use PSNow which is a garbage service but they offer a free two weeks trail...
