So... 5 day old game, fleet is a single destroyer, four missile frigates, and freighters.
40 million credits...
Can we have some sort of system in place to upgrade ships beyond their regular limits? Say, pay X for more OP/Speed/Flux Capacity/etc.
If you want some sort of balance, you can make it so upgrading one aspect reduces another; forcing you to upgrade that aspect as well for loads of cash. Or take the easy way and ask for increasingly obscene amounts of cash.
Unbalanced? Probably, but if I want to drop 30 million creds on a single ship when the most expensive capital doesn't even come near 1 million; it may as well be unbalanced.
