Cadaver747: Considering Take-Two is going to release Mafia Trilogy they might want to do the same with both RDR games, and if they also add the prequel Red Dead Revolver - OMG!
Mugiwarah: Take two never said that their games are badly coded to port them to PC and they are already on PC in their original version (Honestly only the first one needs a remaster not for the graphic but the gameplay is too old now)
Rockstar stuff:
The thing about RDR1 for PC issues was from a Rockstar dev.
You have to remember, Rockstar is not known for good PC ports normally in the first place. Pretty much - GTA3, GTA SA, GTA4 and Bully were atrocious with issues galore upon release.
They were fixed up with patches later though, of course.
GTA5 and Max Payne 3 were great PC versions though - ran well and looked great.
About Mafia series from 2K Czech and Hangar 13:
Mafia 3 still could use some performance boosts. Still not the best running of games. And certainly, M1 could definitely use a Remaster and/or that awesome rumored Remake.
