Short answer: Haven't decided, but definitely not that high.

The RP is likely going to start at around 6 months or so after the Androids' defeat. This gives Trunks plenty of time to search the world for the people he will train and get them started on it. It also allows for enough time to pass that word of the Androids' destruction has spread pretty far and rebuilding has started in some places. In other places... not so much. One aspect I plan to implement is that, in the wake of the Androids, law and order simply doesn't exist in some parts of the world thanks to the widespread destruction they caused, resulting in a noticeable rise in bandit gangs raiding city ruins for whatever they can loot. Other places might have been taken over by crime lords or the like who would see this as a golden opportunity to make grabs for power since the governments are still in bad shape.
