For me it's worth more then $300 - also bought a "kit" for CCC and the Bop 2.0 kit -> no regrets and worth every $.
But if you make a change on the rules... I hope it's possible to do more then one or two little updates, so you could create a more fun game maybe...
I would like to try out some stuff, but i'm not in coding and i think you have to get the original code to do some changes?
Or is it possible to write all code new with p-roc?
