I just played through this and... some elements may end up in my mod...
I am extremely biased (guess why
), so feel free to ignore parts of this post.
The setting and plot might be a bit iffy (see disclaimer), but the missions were action packed and a lot of fun. I found missions much easier when I gave all my wingmen giga lasers (the Scarlash), though some did seem a bit BOEish (fitted the context, so I don't really have a problem with that
I liked the music. The retextures of the nightmare ships also looked very good. However, with shivan vs shivan battles, my whole screen was filled with flashing red and black (probably not something you can do much about).
The shiny capship problem other people have mentioned can be solved by mucking around with the alpha on the texture shinemap (you tested with environment mapping on, right?).
I remember spotting a couple of errors in text (few and minor, and not too big a deal, can't even remember where I found them).
I'm currently trying to figure out a good way to make animated glowmaps for the SF Gorgon in line with the mediavps (hopefully in an automatic and generic way so other shivan ships can be done too), so you might be interested in my results when I'm done.
Ditto for normal maps.
Have you considered using autoaim for the seraphims? This can be highly unbalancing, though. That and it requires a fairly recent build.
Have you also considered going all the way with the interface screens?
It's fun. Go play it.
