What's the complaints? If you change the art style then you lose the aesthetic connection to the originals. It's on Unreal Engine, the gameplay is modernised now and the visuals are much improved.
Rockstar have been threatening legal action against the mod developers on the pc version which have been in existence for 10-20 years suddenly in the last couple of weeks since they announced this cheap money grab.
Why now and not 20 years ago, perhaps because they are of a better quality then their remastered edition and they wanna pretend this isn’t the case.
They have also completely removed the original versions of the game to buy so you can no longer by the versions these mods worked on.
done minimal upgrades I could run the same game through an emulator and bump up the resolution and Anti aliasing anytime in the past 10 years and achieve nearly the exact result.
They have re released gta 5 on the PS4 and ps5 already for a money grab while milking the online side since the ps3.
Not sure there is much to like about the current rockstar since the main man left.
