Apparently, no one told Rockstar Games never to look a gift horse in the mouth.
Before Grand Theft Auto: The Trilogy — The Definitive Edition came out, you could play GTA III, Vice City, and San Andreas, all without problems on all modern platforms save for the Nintendo Switch. Plus, if you game on the PC, you could mod the aforementioned games all you want and make them look just as good as GTA V if not better. For some reason, Rockstar Games had to mess this up with the GTA Remastered Trilogy. It's safe to say that the results have been disastrous.

Apparently, things got so bad that it scared Rockstar enough to cancel its plans to remaster GTA IV and Red Dead Redemption.
Tez2 shared this info about the canceled remasters of GTA IV and Red Dead Redemption on Twitter.
It's not the first time that we've heard about Rockstar coming out with remasters of GTA IV and Red Dead Redemption. However, this is the first time we have heard about Rockstar abandoning its plans.
Take-Two Interactive recently revealed it had a massive slate of games planned to launch between now and 2025. At the time, many assumed that the lineup would include the now-canceled pair of remasters. But, if we believe recent information, this isn't the case. At the same time, the cancelation isn't bad news either. This just means that Rockstar Games is all in on GTA VI.
