everything's a queen!

The other day I created a new varient of chess that I tried with my little brother and it does indeed work (i won by the way).  It's called "everything's a queen" or "queen's chess", and it's played basically as the title says:  everything on the board is a queen except for the real queen (she's a superpiece, which moves like all of the pieces on the board combined) and the king (moves the way he does in traditional chess).  The goal is the same as in traditional chess, and the battles are always very epic (what's not epic about a fight with 15 powerful pieces on each side!?)  Try it out and tell me what you think! :D
