RPG themed chess has been around at least since Betza's Way of the Knight from 1995. (http://www.chessvariants.org/crossover.dir/wotn.html). Like your idea for earning upgrades, which need to be more liberal than those in Betza's game, since his upgrade ranks increase power more with each upgrade. I can't rate this game "excellent" without playtesting it, but a solid "good"
for your idea.
