I'm a bit skeptic of the game because it's pushing higher prices in the industry while being totally unjustified.
But I'm not surprised at all? Like, all of these things the game does were/are entirely possible within the FiveM scripting API. Take a look at GTA RP servers like NoPixel, they've been pushing the limits so hard on a 13 year old game.
And the same API exists for Red Dead 2, which has a visual upgrade over the engine used for GTA V.
I don't know, I guess I'm expecting something to be wrong since it's very frequent and common nowadays for AAA games to ship broken and incomplete.
I hope I'm wrong, though.
