[Gameplay] I'm not liking the global resources.
After playing a few games, I have to say that global resources have some negative consequences. It certainly eliminates some micromanagement, but it completely trivializes the value of real estate and infrastructure. I can build whatever I want, my most advanced military units, even on a brand new outpost without any concern for logistics. It matters not that I had to escort my pioneer to this place with half my army because of the deadly expanse of forest filled with terrible monsters, and it really should matter. It's alot funner if it matters.
Another thing that devalues real-estate is that you can spawn resources by researching techs. You build a city any old place with enough room, and eventually it will justify itself after the fact. It seems a little goofy.
These two things really take alot of the fun out of exploration. You don't want to lose one of the X's. You only have 4 and 4 is better than 3 in that regard. It also means that it doesn't really matter which of an enemies city you conquer, because they're all kinda the same with resources spawning in after the fact.
Each city shoud have it's own pool. Caravans could be used to spread some of the resources around (maybe creating a percentage of the source cities income in the destination city).
