I'm not sure it's worth playing seriously on the computer, but I think having something visual is good so people can learn and then play on paper when they're waiting for their food at a restaurant or something like that.

Maybe not, but Words with Friends wasn't worth playing seriously and look what happened with that. I could see psycopaths creating 16 x 16 tournaments out of this. But regardless of that, it's almost winter here. I'd install it, play it, and share it for paper play. It took me a few rounds of playing alone to see where this could get really entertaining.
