More pin 2k would be cool. I love RFM and SWEP1
How about a CFTBL pin2k, that would sure eliminate holo problems, that would be a cool re-release.
For a new title I sure would love a rugby league pin( although it will never happen ) based around state of origin and in pin 2k that would be insane!

A Rugy League or similar sporting theme would be good for Pinball 2000 because they could have different team colours you could select in the graphics. Another one would be Champion Pub, it is practically he same except it has the boxing bag/boxer figure instead of the monitor. With pin2k the fighter could change appearance.
