I can see it now. The LR BATTLE ARENA. Pay only $10 to gain entry, then each time you die in a fight you have to pay $5 to restart the battle over with packs of new monsters being released in $15 monthly DLC bundles. In order to get the best ending in Lightning Returns you need to buy and beat all of the LR BATTLE ARENA content whilst accepting a monetary charge every time you press the X/A button.
