After watching "Pilgrim of Eternity" on Star Trek Continues (thanks, John!):

I had an idea for a power.  The being with this power absorbs worship and converts it to energy.  Apocalypse of Marvel and Darkseid of DC might be said to have this power.  Any ideas what it would do?  Power recharges at a rate of one per minute of rest, so there's really not much need for that unless you want to treat it like Underwater Type B where the Power score is automatically replenished while being worshiped and unable to regenerate when not...?  Or, Power is unable to regenerate when people stop attending worship ceremonies for the "deity" instead of "not worshipping at this moment."

...or something like that.  Anyway, I've noticed that deities always "wither and die" or whatever in stories about them where their church falls apart.  Thor and various Norse gods of Marvel seem to be the exception, although I think I've seen "rumors" in Marvel about there still being Norse god religious groups running around...?

One of our GMs ran a story where in the Middle East some alien beings got their power from being worshipped by the masses.  Our heroes ended up mounting an "anti-propaganda" campaign that seriously weakened them and allowed them to be defeated.

That was a good thread.

Another idea that way had been in that thread (or not) is an increase in a powers ability for every "X" amount of worshipers. Maybe make it necessary for a geometric increase of worshipers each level increased to keep things in hand.

The Egyptian god Ra
10 worshipers = 2d8
100 worshipers = 2d10
10,000 worshipers = 3d10
etc

Add blast radius and other effects as GM warrants.
