Currently wars are incredibly expensive for large players to get involved. It makes it so everyone has to be peaceful because they know they won't have enough money to maintain fighting those players. Here is what I propose that could fix that.
Make it so that money can be obtained by destroying another players colony. Maybe a percentage of their total bank.
Increase the money displayed in bank and owned by players to be stored in a 64 bit integer.(wars amoungst large players would cost more than 2.1 billion space bucks)
Both of these things would also have the added benefit of encouraging players to destroy old 1 star empires that haven't played in years and have several million saved up. I believe that having this in game would add incentive for players to stay because wars would become profitable. Active players could also enjoy fighting each other with more and could possibly win if they tried hard enough.
