I quite like this, there is some visual glitches and some things that need rewording but all in all it's cohesive and seems fun to play.

• You forget to move the triangles on the tech cards.
• I'd add a harder white/black border to the icon, as well as a radial gradient to make it seem like you are shining a light on it. Most, if not all, of the real faction icons have this.
• I'm not a fan of the cutesy 3d models, but that's personal preference and you should go with what you like.
• Flagship is a straight up better version of the Arborec, which I love.
• Mechs being deployable PDS seems fun. I'd maybe not make it a skip as well though.
• You either can't stop them from scoring victory points, or they can't score victory points if the doozeg isn't in the home system.
• Yellow tech giving you 6 resources and a skip for destroying a PDS is way OP, especially combined with the mechs and bio-stims.
