It seems that the time span of this game is big, and the producer can’t realize it if the time proportion is what I expected, 3:1. Then, could producers consider using ruleset editor to give more handling of the game to players? Let the story written by players. I assume it can use a time scale like Sim City to help players experience the change of era. But within an era, let players handle between rush hour , weekend, night and normal weekday time. To help players get started quickly, set a default rule for all. Once a player get experienced, he can make the game more suitable for him using advanced rules set by himself and play endless hours in it.
