We're testing it.
It may have been using playing cards and spare change, but it showed that both it was fun to play (aka the people we got to help wanted to keep going) and an AI was really easy to make (we could easily play as an AI on several different difficulties by simply looking at the board).
But yes your right gameplay is much more important for a game then almost anything else. To get some screenshots going we're going to have to finish making the models we need for the game. Ugh...
