I had an idea: if there's a race, there should be a god that it worships. That's how it was with all nations, and probably will be in the future. Why not do the same in our game? Each race has its own god. Every week, they bring offerings to him (a sacrifice or some kind of resource), and he (the god) gives that race some kind of bonus. We could create a "collection" of this god, and when a hero collects it, they would receive a super ability. Maybe this has already been done...
