Okay here's a brief explanation of why the rp should be based on the Mega Traveler system but not wholly.

Interstellar travel
Interstellar travel is through the use of the jump drive, which moves a ship through "jump space" a few light-years at a time. Each jump always takes about one week.
Using this method of travel means that space is truly the vast emptiness it really is and the starships are almost like the age of sail where a crew leaves home port and may not return for years

Limited communication
There is no faster-than-light information transfer – meaning no ansible, subspace radio or hyper-wave. Communication is limited to the speed of travel.
Again this means that like the age of sail far-flung Empires are difficult to maintain and information about what's happening in the direction of travel always old and inaccurate, also it means if we break the law in one sector of space all we have to do is keep ahead of the communications carried by other ships

Feudalism
Relatively slow communication speeds mean that local rulers cannot be directly controlled by central authority. Therefore, affairs are managed by independent nobility, who make use of classic titles such as Baron, Duke and Archduke.

Jump Drive
The key characteristic of a jump drive is that it allows a starship to be instantaneously teleported between two points. A jump drive is supposed to make a spaceship go from one point in space to another point measured in Parsecs (A parsec is equivalent to 3.26 light years) and the max jump drives are Jump 6.
While in jump a ship is untouchable and untraceable and it takes one week whether the distance is Jump 1 or Jump 6
