The Core and Resource Base default models. Our streamlined RTS only required one main core and a single building per expansion, and I wanted the base versions to be clean and iconic - with a view to have all sorts of cosmetic versions down the line.
This model went through a LOT of versions but the final in-game models were by Nic Reid, including a bunch of sweet cosmetic variations.
