Cities in game

Thinking about creating concerts I realized that in order for it to not just be abstract "You held a concert in an unknown place - 30 fans" you need to add some depth and this is what led me to the idea of cities in the game. The game will have fictional unique cities, each with its own studios, bars and so on, in addition to this you can of course travel between cities. You can say that this is inspired by "Rising star" where it is almost the same, only the cities are generated.
