Here is the current state of the mod:
Ship models & textures: 80% complete
Structure Models & textures: 20% complete
Tech Tree & other scripting: 0%
Particle effects: 90% complete
UI icons: 0% complete
So as you can see there's still a lot of work to be done. The good news is that once the models and art is done and I have completed a skeleton structure for tech trees, there will very likely be a beta release because I'll need testers anyway to iron out the bugs which will probably crop up in the scripting. So its not about polishing, its about releasing a complete mod, without placeholder art, because I hate that, it wrecks immersion.
