Since I just want this to come to fruition, I'll explain what my intended launch strategy was. I'm a developer (just a contractor, not owner) of Tabletop Simulator and do some stuff in that community where there's an overlap between physical tabletop and digital. My plan was to launch a card game (largely designed) and the e-ink cards simultaneously via Kickstarter. However, before that, a digital implementation of the game on TTS. Basically as much as I love this idea, I couldn't see it being monetisable on its own unless you can bring the cost down significantly. It also didn't seem like a defensible business on its own. But if the product is a game that uses said functionality, well, that'd be just swell.
Anyway, congrats, this is awesome!
