Before I forget, might as well shoot this out - interface art. (Forgive me if I sound senseless 'cause it's 2:30am here and this was something I wanted to bring up a day or two ago, but forgot till now, so I don't quite remember what I wanted to say.
I know Inferno will be using sensible damage bars as opposed to the daydreaming-inducing rotating tech displays, and that "use models for ship selection" is a requirement, but IMO it would be nice if each gun had its own individual icon. Maybe just edit the existing icons here and there to denote gun variants, and use totally different ones for any of the new weapons. But the only thing I can do is manual pencil-on-paper drawings without a ruler that don't give a thought to accurate dimensions...
Say maybe the Avenger II. Perhaps a slightly (and visibly) different icon to tell it apart from the Avenger? Or perhaps in the case of Inferno SCP when you have a mission where you can choose from the entire Allied and EA fleet combined - it would be a bit confusing to find an EA gun/missile share the same icon as a GTVA one. (Shivan weapons on the other hand... naah I don't expect Shivan campaigns to be commonplace
It doesn't matter much (player just has to look through the inventory screen carefully instead of rushing through as always), but I think it's the overall presentation that counts.
