The image you posted just looks like simple shading. Not lowspec.
I'm curious about the cards though. Could you post some of them here?
I think this sounds pretty interesting! I added the kickstarter as a reminder, if I'm not totally broke next month I might support it!
I'm not sure if I'd ever play this in 'meat space' though..
You should look into Tabletop Simulator, it's really simple to add custom cards and I think they're looking for games to sell as DLC.Edit:
Looking at the kickstarter, there isn't much high res art and the product images are very tiny, I think potential backers would appreciate seeing the cards and box in more detail.
