maby this would be a good mod idea
maby fleet supply should be based on how many planets you have, so that you can research those upgrades but, those simple make planets give you more lets say at start you have 25 per planet and a free 100 for your home planet you caoture two planets, now you have 150 cap, you research the 1st one, which is 150 for home planet, and 50 per planet, now you have 250, and you capture two more you have 350. so that you gain the ability to make bigger fleets the bigger your empire is.
if some one has an idea of how to make this tell me I would liek to make it my self, but if you want to make it you can too.
