UPDATE
So, roughly one year on (though not been full time job, lol)
finally finished game and first pass of changes. Some new pics below just to show selection of some of later mission changes. As per original post, now changed all guest anims (Data, Korbus, Saalek) so work on new EBridge; all major viewscreen/set/character backgrounds; outfits, etc. Changed Khitomer from Nebula to Sovereign class as flagship and launches shuttles (changed from Type6 to Type11).
Next stage is to make another pass and refine some of outstanding issues/bugs.
* tweak/refine mission scripts
* tweak/refine D & E bridge anims
* tweak/refine ship hardpoints and balance
Once sorted issues out will obviously post complete changelog list and package for betatesting. Been a useful experience as learned a lot, especially how mission scripts work; how to do motion flow animations; creating new game figures. Opens up new potential for custom mission scripts.
One last thought about variant mod. There's potential to do TOS/TNG versions if can change "Cardassians/Kessok" in soundfiles to Romulan/Klingon.
