Research!
Soon to be introduced, a Research lab building that will generate resources depending on its adjacent buildings. Extractors grant red, Solar panels grant Blue, and anything else/nothing grant green. For now.
This science will be used in a what will eventually become, a huge research tree. Starting with some very important things to make the early resets a lot easier will be things that make your units stronger every xx levels. The way they stand right now is quite linear, and a level 150 unit artillery can still destroy a level 250 weak unit. Although that is by design by being a counter so to speak, Research will help this struggle players will find in the <150 level area.
Research will be used for a lot of other things, One of the most important ones will be the concept of making upgrades cheaper so you can get to higher numbers quicker, and make them resets less work.
