With GTA 6 three and a half months out, it's a fair question. Short answer: yes, if you're already invested in a character โ less so if you're starting completely fresh this late.
The Case For Playing Now
Rockstar hasn't slowed content updates, and GTA$ and RP earned now don't disappear when GTA 6 launches โ GTA Online isn't going anywhere on November 19. Property and business investments still pay off over a normal play session.
The Case Against Starting Fresh
New players face a steep grind against players with years of unlocked businesses and cash. If your only goal is experiencing GTA Online, that time might be better spent finishing GTA 5's story mode instead โ see our GTA 5 Guides for where to start.
Our Take
Existing players: keep going, nothing is being taken away. New players: treat it as a bonus after the story campaign, not a reason to buy the game on its own this close to GTA 6.
