Rockstar makes multiplayer titles, but doesn't have an engine that's capable of dealing with that (leading to an absurd number of bugs and performance problems), and they have no security at all, so their games are only playable on not-yet-cracked consoles. Rockstar even went so far as to include a "finger of god" feature in GTA, which allowed their admins to kick players from and mess with the single player mode, except Rockstar has no security, so mod menu developers figured out how anyone with a menu could use those features to mess with literally anyone's single player. They eventually removed that feature, which as I recall is one of maybe two or three times they fixed a security problem. Previously mod menu users could reset character stats and outright ban other players. It's incredibly broken, even though financially successful, based on ethically questionable marketing of ingame purchases to minors. RDR2 may be beautiful, but performance is bad. RDO runs on the exact same system as GTA, so zero security and unplayable on PC.
