@TheJackal84 - There used to be an app (on IPB v2.x I think) called IBProbattle.
Basically it was an RPG style game where you attacked fellow members (who could opt in or out of the game) and based on what weapon, armour, health etc that you and your opponent had, a winner was decided. You went up levels earning XP. You could buy various things from the shop, weapons, armour, health potions etc.. Every time you battled someone you had the chance to steal some points off them (think they called it gil back then).
Done a bad job of explaining it, managed to find this link to a site professing to be the official site for it, although TBH, I don't remember it being that site when I used it
I remember it being free so you may be able to get a copy and have a look at how it works if it is of interest to you, depending of course if you need / can get hold of an old version of Invision
