Currently we have a 10 credit upkeep per hour. It feels way too low and it does not take into account the size of the ship. Further a good sized planet of around 1 million population would be able to support around 500 ships and 500 battleships at that, why build smaller…
i propose that the cost be 1% of the credits cost to build the ships.
e.g. scout is 890 credits to build so the upkeep should be 8.9 credits an hour.
e.g. battleship is around 12000 credits so the upkeep should be 120 an hour.
I also propose that ships in fleets reduce upkeep by 25%
I further propose that ship and fleets in orbit incure a further 25% reduction to upkeep (so stacked to 50% reduction)
So 5 battleships in outer space and not in a fleet would be 500 credits per hour
in a fleet it would be 375 credits per hour
in a fleet and in orbit 250 credits per hour (500/375/250)
so back to the good sized planet it would only be able to support 40 (80 in orbiting fleet) battleships or 130 destroyers (260 in orbiting fleets)
