I think the rpg element such as buying food, clothing, building strength and cardio are what made san andreas so great, and SA to me and other gta admirers is still the pinnacle of the gta series.Also the amount of weapons and vehicle choices was amazing as was the mission variety.
Will this game have rpg elements what is the probability it will have?
To me this game will only exceed san andreas by having large mission variety+rpg elements/customization+ and some sort way to interact with the narrative.
I really want to just flat out say "it won't" since R* already said there won't be any San Andreas style rpg elements (such as requiring to eat, building muscle mass ect) but... I'm not one of their employees so I'll just stick to: I HIGHLY doubt it
