Why not just make ships need a power/fuel supply? First, the addition of fuel cells or tanks would instantly drop the available number of spaces on a given hull. Second, a ship traveling at it's normal rate (let's say anything less than 8 since that seems to be the magic number) would incur little, if any, fuel/power consumption. Once a ship breaks the 8 spaces a turn rule, fuel consumption would rise exponentially. That being said, player's would have to be more mindful of how they wish to deploy their fleets and in what time frame they would get there. To stave off the inevitable "then how do you refuel?" question, the fuel supply could be regenerative (sci-fi to the rescue)i.e.: You send a fleet into an enemy's territory at full speed. Even though you make the trip in one, maybe two turns vs. the twelve plus it would've taken at "normal" speed, you find that your ships are severely drained of power, pretty much making them sitting ducks until your power supply can recharge itself. I think this would be a viable option for the devs to entertain. What do you guys think?
