Here on Earth we have more than 6'000'000'000 people. This game wants to populate a galaxy. There is a problem here. With a 1:1 scale it would be impossible to "populate a galaxy" densely enough with a small fraction of the Earth's residents. It would also take an impossible amount of time.
There are two different adjustments needed to solve the problem:
Compress the spatial dimensions. Compress the time line.
For the following calculations I make a simplification of assuming 6'000'000'000 people on spherical Earth, and radius of 6'000 km. Those numbers give an image of a planet slightly smaller and less populated than in reality.
After thinking for a while I decided to go with a simple division of distances by 1'000. So one kilometer becomes one meter. This goes nicely with 6 million players (World of Warcraft topped at 11 million) being one thousandth of earthlings.
After compression, the above, assumed planet becomes one with just 6 km radius. From 453'600'000 square km of surface down to just 453.6 square km. The surface actually decreased million-fold - that means the six million players would need to be scattered to a thousand planets to stay at the same density level! How does that sound as "populating a galaxy"? Realistically, six million players is a high target to clear and a thousand planets all packed with players is something mind blowing as well. When we consider a start with just one planet, six thousand new players sounds like a good success story for a well hyped game. Even if we start with less, that just means more free space. One thousand per arkship? Sounds like sensible, story compliant number. It also gives sense for existence of six times more planets. I may have pulled the ratio out of my ass as the saying goes, but it fits surprisingly well.
However, even that shrunken universe would take a lot of time to traverse. The closest star to Sun in reality is 4.4 light years away from here. When divided by thousand, this distance shrinks to 38.5 light hours. That is still way too long for a short distance trip in a game. This is where the time compression comes in action. From the same place as before I hereby pull out another ratio - 1:60. Imagine the minute hand of a clock moving ahead every second. With just that a travel at "speed of light" to the Sun's Nearest Star would take 38 minutes 30 seconds. A jump from Sun to the end of the Solar System would take only 15 seconds. And that is not considering the Faster Than Light engines!
What do you think of that?
