Want to start a multiplayer streaming game for 6 people

I haven’t played in quite a while and it was before they updated to 4.0. (I remember biogenesis coming out soon after i stopped playing).

My streamer friends want to make a long form game for streaming and I’m wanting to know what settings I should change in order to get this to late game. No mods btw.

(Also still getting used to posting on Reddit so sorry if I mess up somewhere)
