Then explain why I have 5 spots in my colony tab :P 

And only 3 of those produce resources.

So the "only 3 are called colonies" is kinda sily

The other ones are potential colonies XD

I think the game lists them in order of when you invaded them, and they also go in that order for when you lost them as well, so you can collect resources from them.

Need more Resources to train Troops?

Colonies are the best and most satisfying way to improve your Resource Production! Invade rival Sectors and make their Resources work for you!

Remember:

- You get more Resources from high-level Sectors owned by active players.
- You can only hold 3 Colonies simultaneously.

War is all about competition. Get out there and take what’s yours!

Btw, you can't produce credits from colonies.

Commander LOCHLAN297, you're absolutely right! Credits can't be chosen as resources received from a colony.

I know I am right.  Lol

I know I am right.  Lol

Any way what I really wanted to say was that credits are the main resource used for training troops so how does invading sectors help if you can't get credits from them? Apart from getting your ranking up in the hall of fame.
