"In Orion II, none of the worlds, not even gas giants
had moons. Also, all of the gas giants were all the same size and
not one of them had rings. Having features such as this would make
the game so much more realistic."
You can have up to 256 stars, each having eight planets, each planet
having five moons. Imagine how big the galaxy of MOO will be - that's
a potential 12,288 worlds to colonize and fight over.
Quicksilver's philosophy is that gameplay has to come first. So
any decisions made based on "reality" also have to be fun. On the
other hand, though, QS's trying to be as realistic as possible.
So they've done a ton of digging into current astronomical research,
and the following points are in the design already.
A All planets can have moons, including gas giants.
B Gas giants can certainly have Earth-sized moons. In rare cases,
you can even get a double planet.
C Asteroid belts are included, and they affect combat. Not sure
exactly how stray asteroids will enter into the picture, but they'll
certainly be considered.
D There are brown dwarfs - that's basically the biggest-sized planet.
Naturally, it takes a little time to get enough technology to make
use of such things, but that's part of the fun of the game.
E There are lots of variety in the star types.
