It was my peerblock firewall. At one point the game's IP address must have been used by a spammer so the moment I disabled my peerblock software firewall it went right through. I'll add an exception to the list.
One way to separate power levels without tamping down on refresh (which is certainly an option), would be to gate your stunts or stunt equivalents. If some people - say dragons and cyborgs - get access to stunts with stacking bonuses and your average beat cop does not, then even at equivalent refresh the former will in theory have an advantage in their specific areas of competence. Bear in mind that situation aspects and the 'create advantage' function of many skills can serve as an equalizer in these kinds of interactions but that's probably okay?
I think a good question though would be 'do you want to hack fate specifically or would you want something more pre-packaged'. Because there is a LOT of Fate out there that can be used. Legally, even (thank goodness for that CC-BY licencing scheme).
@RDC - I do quite enjoy the Heartstriker books and the DFZ setting, at least as reading material.
(To be fair, I basically just love anything Rachel Aaron writes: the Eli Monpress fantasy epic, the Paradox SF trilogy, the Heartstriker/DFZ semi-post-apocalyptic urban fantasy, the Forever Fantasy Online LitRPG books... she hasn't really misfired yet in the stuff I've read.)
@Thenomain - you cad. I spent some time wondering WTF contract that was. 😉
I'm a little short on RP because staffing, but I'm happy with the players I am working with. They've been very flexible and understanding. A good bunch.
