Rockstar despite having terrible work conditions has some literal wizards in their studios.
The technology they have in GTAV & RDR2 with their commitment to simulation drags all
these other studios.
A.I. that knows when it's being stalked, when it's being insulted, when you stare at too long, contextual behaviors
based on whether or not the A.I. is more timid or aggressive, etc.
That's without considering the dope as physics and animation systems combined with the A.I.
This makes A LOT of other open worlds seem static and boring in comparison.
Hopefully this changes with this generation and we get back to dope simulations (Far Cry 2 TO THIS DAY is still smoking
many FPS games on the simulation aspect.)
