you should make a starting system with "tutorial" commodities and "tutorial" missions that will explain the new players how game mechanics works and maybe trow in some scenarios that will explain some basics rp and diplomacy between some factions
as for cortez vs penny, while you've got complaints from other faction leaders stating that the reason why they don't join those is that current starting system is situated in liberty that is further from the true, by that i mean if you move it they would still move there after they start up because they are more comfortable with american doctrine rather then Asian or Germany or french
People want to believe that God has a plan for them.
They don't wanna believe that anyone else does..
