Postcard Games
While organizing my computer today, I found the files for the Symmetric postcard game.

I really like Symmetric, but it didn't do all that well for me and the publisher gave me the rights back. I'd like to expose more people to the game so I want to find a way to self-publish. But, abstracts don't sell very well in my experience and given the mechanics, any theme would feel very tacked on. So I can't really justify to myself trying to raise money for a print run.
So, I'm considering selling the postcard instead. Postcards are inexpensive to print even at low quantities so they could, in theory, be a very cost-effective way to publish simpler games.
I would welcome any thoughts on the matter. Would you ever consider buying a postcard game?
