Yeah, routes really should be able to transfer Production, Science, and ESPECIALLY CULTURE. Seriously, so much of the world is influenced by Hollywood movies alone. Obligatory reminder about resources increasing commerce, obligatory reminder about great works being implemented.
ALSO WHY I FUND PRODUCTION? Why can't I convert commerce to Production (giving better funding to state projects) in order to increase my %Production? I know Production isn't a commerce type like Science is, but the Production slider should be a thing. Ditto for Food, Military Success rates, Stability, the culture slider really should give happiness without requiring buildings, and why can't I set my sliders to increase the rate of development of the next Rhyes and Fall update?
