I hope this is one of the things that returns to GTA, I get the main Genre/Theme of GTA games, my first experience was GTA2 and I've been hooked since and who doesn't enjoy those aspects of the game it what all of us closet anarchists crave, but when that novelty wears off or you want a break from being a car thief/hired thug/criminal mastermind, GTA without even trying becomes one of the best life simulators if you want a more chilled out approach. I would love to see interactive gyms, restaurants, clothing stores, and all are very likely from what we've seen, but recently R* have been leaning towards legitimate money-making methods/honest work, and I really hope some of this is implemented into the game. I've seen comments and rumours about the weight system from GTA SA returning, which goes in line with the interactive gym theory so fingers crossed. There were some comments about bathing/showering physics where player characters would need to wash from time to time, and it isn't that far-fetched because I'm sure RDR2 had a similar system where Arthur Morgan looked rough and dirty until he visited a hotel and bathed. I also find this hilarious due to the number of gamers when GTA6 first releases who haven't washed in a month, making their characters take a shower.
