There have been a few mods similar to this one long before CiV was announced to use 1UPT. I've even made a few (unreleased) myself. One clone of Advance Wars which also uses 1UPT, and another mod which I will probably never release . Those were for Civ 4. I even based my work on another mod so yeah it's been out there. And I wouldn't say Magic and such from FfH2 is really balanced well. I mean even the stack busters from BtS have limitations on how many units they can damage.
