Form: leveraging on 3d models
From showing the cardboard layers of components, to creating the subtle effect of linen finish, these small details really help elevate the look of the game and engages players visually.
Custom models also usually pave the way for more interesting functionality within TTS.
I ended up adding a linen finish to all cardboard components in the game, which was only possible because each component was painstakingly modeled in 3D. While the effect is subtle, it really helps make the mod feel that much closer to its physical counterpart.
