Agree on all points. There's a total conversion mod for the original X-COM: UFO Defense that is amazing, and being actively worked on. New updates every month or so. Hundreds more hours in the campaign. Set a few hundred years after X-COM loses, and earth is a radiated wasteland when some intrepid mutant gals start to fight back against the "Star Lords". It's called xPiratez. Rated a soft "R" for gratuitous pixellated boobage.
