I think the singleplayer, aka the important bit, is going to be good. Leaks looked pretty promising. Probably not going to be as revolutionary as people expect after 10+ years of hype and speculation, but still probably a top tier video game surpassing their previous titles in many aspects. Online is probably going to be biggest shitshow of all time, though. Microtransactions, FOMO, subscriptions, battle passes, the works. Every bad thing about games as a service packed into one, with the additional bonus being that Rockstar can't program a multiplayer to save their lives, so it's going to be peer 2 peer, with the shitties netcode and matchmaking possible and absolutely zero protection from hackers. You know, like their last two multiplayers.

GTA as a service with monthly subscriptions to every single thing you can think of
