Have you tried Chains to Champions? It was just released in March 2013. It is a really fun game where you get to purchase a gladiator, then equip him with various weapons, armor and helmets and then fight to the death in an arena that is surrounded by deadly spikes. It comes with training dummies as pawns but I use Lego minifigs which all the accessories are made to fit. You can strategically create really interesting combinations. It's most fun with a group of people because then you can make alliances, and break them. In the first part you can bribe the auctioneer, in the second part you have 7 days to get training and equipment or can choose to work for more money. I have played it a lot and never made the same gladiator twice. It is made by a company called Brickwarriors. Hope this is what you were looking for.
