Fallout RP? Yay or Nay?

I've been putting serious consideration twords a Fallout RP (due in no small part to my recent obsession with this series). Characters would have their S.P.E.C.I.A.L. stats and the faction system would work rather well in terms of an enemy to fight.

I'm more than likely gonna put this out (though when i have no idea) but i was wondering if anyone had any ideas to contribute?

Any and all comments appreciated
