So many years ago, on the Bay 12 forums, someone was playing (?) / doing a Lets-Play of X-Pony.
Of course, it wasn't real.
Now there's open XCom.
Any chance that we could actually get an X-Pony mod?
As described, it wasn't just a re-skin -- your pegasi are your interceptors (not your interceptor pilots), and only unicorns have ranged attacks at the beginning of the game. (Of course, earth ponies would have a great hand-to-hand attack and can strike behind them.)
