So from what I've seen, one of the big complaints about The Universim that I've seen is that it doesn't feel like a proper god game, so I had a few ideas while eating dinner tonight and sitting here typing all this out on how to put the god in god game.
First idea: Prophets
What if we could have Nuggets that are our prophets, informing other Nuggets of our will and helping to generate belief/god power through leading the other nuggets in worship as well as act as the spiritual leader of our Nugget tribe? Perhaps also being able to perform miracles, as our sorta but not really avatar?
Second idea: Holy Texts
What if we could have our own holy books that our nuggets read/follow, like a set of divine laws set by us that impact nugget behavior? For instance, say we forbid the eating of meat, nuggets could no longer hunt or eat meat, but would gain bonuses to eating food from farms, or the opposite and they get a bonus to eating meat while not being able to farm anymore, which could also impact Nugget evolution due to the changes in diet.
Third idea: Missionaries
So I've heard about exile tribes and how the Nuggets in them don't believe in you, what if we could designate missionaries to attempt to travel to exile camps and try to convert their Nuggets to your faith, thus giving you control of them like regular Nuggets? Of course, there could be a chance that the exiles would be hostile and attempt to kill the missionary, or that the missionary could fail and not convert anyone, perhaps even being converted his/herself?
