"Plot a course to the center of the galaxy and back. 10 billion credit reward"
How long would that realistically take? We could be talking about years of real life game play.
The centre of the galaxy is 27,000 lightyears -+ 1000 lightyears according to Wikiepedia.
The Asp could jump 32 lightyears with a Class 4 hyperdrive.
That would be 843.75 jumps, assuming exactly 27,000 light years is the distance travelled.
Considering that in this game that jumps are near instantaneous, but let's assume 5 seconds then:
843.75 * 5 / 60 = 70.3125 minutes or a little over 1 hour and 10 minutes.
Then you would need to factor in how long it would take you to travel in-system to find a fuel source such as a star or gas giant. Let's say it takes you 5 minutes to refuel at each system, including travel to the fuel source and the actual refuelling, and you need to refuel say once every two jumps.
843.75 / 2 * 300(5minutes in seconds!) / 60 = 2109.375 minutes or 35.15 hours.
So about 36 hours realtime to galactic core. Simply double that if you have to refuel after every single jump.
As for the poor old Panther Clipper and it's Class 8 and 13.69 jump range, using the same values above, real time to galactic core would be:
82.17 hours refuelling every other jump.
I was never any good at Math so I hope this is right.
