I was so excited to see this. A year ago I tried to distill a bunch of popular board games down to discrete rules that could be dropped into a generalized framework. I wanted game designers to be able to quickly model and prototype games. I also was interested in games where the players get to evolve the rules over time.

However, it ended up being way harder than I expected. In fact, I tabled it indefinitely because I started to believe that it was just intractable. (That is, trying to conceptualize a game into a discrete rule set is often a lot more work than just implementing it in code.)

I'm glad to see others trying to tackle this. But, I hope they try to implement games that are significantly more complex and sophisticated than tic-tac-toe though. The current code is so simplistic that I can't imagine that it will help much. That is, if I used it, I'd still have to custom-code 99% of the logic. But, at least it's a start.
