before you choose planet sizes, consider the implications.
larger planets = planets are visible from one to the other. they look large, and the systems look small and compact
to fix it = you spread out the planets.
spread out planets = larger distances, longer travel times without autopilot. travel times are no longer like in privateer.
to fix travel time, you speed up the craft.
sped up craft = dodgy gameplay. dogfighting becomes impossible because the speeds make following-in-close-proximity impossible.
to fix all of this, you'd have to add an alternate flight mode.
remember, this is going to be MULTIPLAYER eventually, so autopilot won't always be an option.
a 'scoops in' mode has been discussed. some mode where your speed goes up a LOT, like 10x. purely for transit flight.
this sorta feature, again, makes the game less privateer like. and actually, less wing-commander like (game-wise).
We'd have to pull in some book-stuff to get that going.
basically, changing planet sizes leads to more things that you have to do. it's not simply artistic.
