imagine all the pokemon game prices times 10, then imagine the only way to get money was through the casino coins minigame or through some menial repetitive task. now imagine have a "+3 monster slots" pack to get all 6 slots to store monsters in your party.
now imagine certain pokemon being purchasable, or some masterball being sold, or tms being sold.
players with a parents credit card would rule and get everything, just like in iera. totally unbalanced, but stefan would get his money, so why would he care?
