but, having fuel would add realism to it, but would prove a burden on multiplayer.
Most ships have enough fuel for weaks. So if you would like to play multiplayer for weaks non-stop, then it will be a burden yes.
I allso don't think you have fuel meters in real life on the bridge.
On small ships you have them, but not on big cargoships.
Some cargoships even still have to be measured manually with a plummet (or plump bob) in the bunkertank.
So I wonder if fuel meters will be available on every ship.
