The average IQ of a colony should have an impact on how productive workers are while at work. One idea that could possibly work is using the average IQ as a multiplier for production and make education buildings have more use than they currently do.
I like this idea! This would definitely add more incentive to build higher education buildings!
The Spice must flow.
Thank you so much for the feedback. Feel free to add your own ideas in too if you would like to.
