Something a few of us have been noticing is a chronic shortage of Supplies. Now I do understand that with some countries, that goes with the territory. However, there is no excuse why even countries like Brazil or the USA and others known to be major food producers should be running out of supplies long before we run out of say, Rare Materials. Especially in 4x mode there is no way on God's Earth, or your version of it, to even come close to keeping up research. Most of the time, between building structures and units, I can only research one thing at a time. Either the demands for Supplies need to be lowered or yields increased, either way something needs to happen. It just suck all the fun out of the game to be constantly stressed by resource shortages.
