They set the bar quite high with GTA 5 and Red Dead, specially Red Dead Redemption 2. The attention to detail in that game is just mind boggling! I hope they put in the same effort into GTA VI. This game series is what I grew up with, so if they screw up this will be quite dissapointing.
I am pretty sure they got a shit tonne of pressure on the development team to get this game right.
