If it's true that removing gem-gen items cripples some nations, then the solution seems pretty simple: Give those nations gem-gen summons. What little I know of modding suggests that the mechanics are there for water, earth and nature gems... can that be expanded to the other gem types?

Edit: Now I see that Fantomen beat me to this idea and has it in another thread... nothing to see here. Move along.
