I tend to see this sort of thing with temples. Lets say you have 5 of the things you can build. One will ultimately give you, say 20%/20% happiness/law. I get that. One might give you like 20% happiness/increase in tradeable good. Okay, I get that. Then you get one that says 20% happiness/increase in tradeable goods AND +2 morale (this is just an example, don't nitpick if I get some detail wrong).

The last one is the one I don't understand, because it means based on this information alone, you'd never pick the one that just gives 20% happiness/tradeable, because the other gives that and +2 morale also.

So, I suspect there are some hidden stats with some of these temples that provide things I don't know about? Can someone explain?

Thanks.
