While the single player story of red dead is one of the BEST I have played the red dead online is one of the WORST. The game is broken, there is constant server error from Rockstar's side. Rockstar has shamelessly monetized the game, the economy of the game is so throttled, that it literally forces you to spend real cash on gold bars to get anything good or do endless grind, even the grind is so boring and bland, the story is barely there, missions are repetitive. On top of all these, the game is full of hackers and Rockstar does nothing about it.
Compared to the masterpiece Red dead redemption 2 is, red dead online is complete garbage.
