"The JJP platform will use open source code to allow players to program their own rules"
As BrokeDad mentioned this also, this is really good news to me. When the game gets too easy or boring, Voila a whole new set of rules!. And if they do it right you could just load rulesets that are stored on a USB thumb drive. Also can you imagine, trading rulesets with different folks or having folks post there rulesets here for downloading?
This open source feature alone gives the game a ton of flexibility. 7Gs is a lot of cash but I'm now tempted to throw down the deposit and go from there.
