As a compromise, our intention was to provide some customization options in the galaxy creation screen (currently you can only modify stars, planets and artifacts). For example we already have code to organize the planets by type and we could put a check box in that area if there was enough support for it. Even if we don't add a particular element you are interested in in the customization screen, many of the elements you want are easily modded into the game.
As sci-fi buff I wouldn personally love to get it as accurate as possible so I appreciate these comments and that is part of what betas are for. If anyone has any ideas that strike a healthy balance between gameplay and simulation we do want to hear from you.
First off, great job so far. I'm very impressed with the paucity of bugs I've found.
I think you will make most people happy (w.r.t. realism) by simply lowering the minimum number of planetoids in each star system in a custom galaxy (the current minimum of twenty is way too high). This will solve the biggest complaint about realism that has been posted over and over again. It really is quite laughable to see several terran-type planets all suspended at about the same place in a star system.
However, I think there are some additional things that can be done to make Sins both more fun and more realistic:
1.) For each galaxy setting, increase the number of stars and greatly decrease the number of planets in each star system.
2.) Make interstellar travel be a somewhat later-game technology and increase the interstellar speed by a moderate margin.
3.) Late game quick jump calculation research should provide a MUCH GREATER decrease in the time it takes to jump from planet to planet. Way too much time is spent in the late game just waiting for your massive fleet to hop from planet to planet to planet.
4.) Some structures in a planet's gravity well (for example, the metal/crystal mines) should orbit around the planet.
5.) Replace some of the metal/crystal asteroids with spherical moons. Give these moons a variety of moon textures (with impact craters) and a variety of sizes.
6.) Increase the variety of sizes for planets.
7.) Increase the size of a star and it's gravity well.
I'm perfectly willing to give up on the colonization of the moon's of gas giants.
Also, a side note: I have enjoyed the planetary bombardment graphics. I'm hoping that the other races have different planetary bombardment methods complete with their own unique planetary bombardment graphical effect. It will get very boring if in every game you watch the same nuclear bomb bombardment over and over and over again.
Please let me know if anything I've said is unclear.
