Ok you get to create a character and pick where your character is from (Country and State) pick your starting place and pick the year you start in from the early 1900's and keep going from there the time would be real time so if it was night here it would be night there depending on were your character is with the time changes and all but there would be rain snow sun ect your character could be anything from a homless man to a gangster to the president or any other world leader.
I would make a Boxer in 1920 from Sicily he'd start out as a poor church gardener in Sicily then he'd flee to america become a famous boxer then in 1935 a enforcer for the mob in New York.
Then in the 1960 he'd be 59 and the head of his own Family in Las Vegas then he'd die at the age of 64 from a shot to the head from a rifle as he was leaving a casino he owned.
