I stumbled across your stuff about 6 months ago, and checked out the TZ rules you have designed. (I have put the correct link in for you as yours didn't work)
https://github.com/SonnyJim/freewpc/blob/v1.0-rc/machine/tz/rules.txtVery interesting project, must consume mega hours
I can understand you wanting to improve rules for some games, but what made you guys choose the games you are currently working on?
Other than BOP and maybe T2, they would seem to me to be complete games with quite complex rulesets.
