I don't have a lot to say regarding game balance issues. I do have a fair amount to say about the art direction of Sins, but most of it would be closing the barn door after the horses have left.
One thing that does stick in my mind, though, is that when you blow up a capital ship, there doesn't seem to be a lot of physics involved. It's just a pretty explosion (and one that goes by much too quickly, in my opinion), and then the thing is gone.
But a capital ship is really big, and so are the space stations and such. My suggestion is that when they are destroyed that they leave hulks behind, instead of getting blasted into smithereens. The hulks could be re-harvested for scrap by the builder ships. Or, if the hulks are ignored, they could spiral into the planet and kill a few citizens. I mean if you can fire rockets into a planet, surely you should be able to crash space stations and capital ships, too.
If we can explode gas giants to create damage, why not have death from above from space junk?
I suspect that this idea may have been thought of already and abandoned (since one could also just push asteroids into planets, which would ruin the economy), but on the off-chance that this is an original(ish) idea, I present it now for future consideration.
