Alas, a project to bring Red Dead Redemption to the PC using Grand Theft Auto 5 has come to a sad, yet predictable end. It appears developer Rockstar and publisher Take-Two didn't take the work of modding group White Team too seriously... that is, until it released a trailer. Shortly after the drop, the video disappeared from YouTube, followed by confirmation from White Team that it had been, er, contacted by Take-Two.
When the clip went missing, users posting in the mod's announcement thread on GTA Forums speculated — correctly — that Take-Two had made a move on the project. White Team representative and lead programmer, Mr. Leisurewear, soon corroborated the rumours:
I know this is hard pill to swallow, but as you may have noticed we did get contacted, and we sadly have to say we are stopping this project. So thanks guys, we were all so happy to see this, but it isn't going to happen, sorry.
It's revealed a few comments later that the mod had been "3 years" in the making. While it's unfortunate the project has been shut down, one has to ask how wise it was to pour so much time into the endeavour without getting some assurances from Take-Two or Rockstar first.
