@ominous Awhile ago...almost a couple years now, my friends and I were running a game set in Gotham City during the Flashpoint Paradox. We tried working out a system that was simple (but could have been better), but it folded due to a lack of state support (we're all in Australia), and due to our coder having a accident.
Either way, we still enjoyed the setting a great deal and could think of ways to simplify it and allow for play we can keep up with.
