This is how Planetarion worked in 2000 and this is how Lords of Ultima and its ilk work in 2010. You build units (better ones can be researched over time) that then allow you to plunder other bases for even more resources and build even larger armies. The games I’m talking about here all follow one basic formula: You gather resources through structures in your home base that can be improved for a cost to produce even more resources.
