But the GTA V that people play today is not the version from 13 years ago for PS3 and Xbox 360.

We are on the third-generation of GTA V with the enhanced edition that only came out on PC last year, and Xbox/PS5 4 years ago. The latest version has 18x the pixels per second (9x resolution, 2x frame rate), and far more detailed models and textures than the Xbox 360/PS3 version.

It has been profitable for Rockstar to keep remaking the game with better and better visuals specifically because consumers are demanding it.
