More color pallatte?
One move we made was making tech tiles the same color as their tech tree and I think that has been a fantastic success. One new change I would like to suggest is making the races of the same color slightly different shades. This would make it easier to differentiate when scanning multiple games.
ex. Taklons and Ambas can be a few shades lighter/darker from each other. It would not be have an impact in an individual game but would add some character and uniqueness when scanning multiple games or playing multiple games. Just another little way to provide information tothe players without making huge changes.
This is something not really seen in the board game bc of the limit in pieces, it would not make economic sense, but would be easy and beneficial to implement online.
