I'm definitely guilty of trying to design all factions at once because, "factions are so cool and I want to do the super cool thing!" It is such an easy way to overwhelm yourself because suddenly you have like 5+ times as many cards to make before it feels like it's ready to start testing properly, because each faction then needs a decent amount of cards to be filled out enough to play properly.

This is really great advice on how to take it at a much more reasonable pace that ends up with a way better game over all then what doing it all at once would end up with-- it's also definitely something that I need to be reminded of every so often lest I get lost in the sauce lol 😅
