Making a realistic simulation like this would take a lot of time and effort, especially for an individual

even games like gta which have a huge team of professionals cant do something like that. yes they made a huge city with lots of people, but they dont have unique daily routines

and stardew valley didnt even come close to what you are trying to achieve. the game only had a small amount of people and the map was small

even if you made the perfect simulation the game will feel empty in a way.

people in gta. they look unique, but feel the same

hope you got my point, i would like to hear what you guys think :)
