How did you do research for "the history of the entire world I guess"
spend weeks learning everything about something (such as a 500 year period of history of every part of the world) then slam my head into the wall for several days trying to come up with a way to sum all that up in less than 1 second in a way that is fun, enjoyable, coherent, and seems chronological despite having to take care of multiple separate plotlines simultaneously. oh and not anger 98% of the world by leaving almost everything out. and then repeat the process for the next few weeks
