Hi, if you are interested in both open world game and online I have a great idea and crazy game in mind, please at least listen to my opinion .

3 countries, 10 cities, private life, style and profession. all players need one. For example, house architect, car engineer, police for city security. Again the war will be between the country.
some players will do military service.
Briefly normal human life
I have more content ideas.
A first in the world.
Imagine that human life is a game .
they will have their dreams in the game .
