IMO there could be some more variety in some cases:

1. Seems like all (?) missile types look the same in the battle viewer? (to be clear, I mean the visual effects produced by those weapons in battle, not the module gfx)

I did only research as far as photon torpedoes, but they seem to look identical to stingers, harpoons, phonotic warheads gfx-wise in battle. Personally I loved the StarTrekkish photon torps in GC2...can we have those please

2. I'd like to see some more unique gfx/icons for buildings - it seems there are quite some reused?

Ok, all of this is just "eye-candy". And yes, great game is more than great visuals. Also, I fully understand that reusing gfx/weapon FX might be simply a way to reduce workload (after all, someone has to implement all of this).

Still, some more variation here would be nice IMO....
