Interestingly, there is quite a lot of game theory applied, though strictly in regards to monetization at this point. The capsule machines, time limited stock of items, and low priced carnival events are well considered here. With regards to player rankings and competition (typically areas seen heavily designed with regards to game theory) there is very little consideration apparent in the current state of the game. Monthly leaderboards for bk, pk, as well as spar rankings, are encouraging players to cheat or find means to generate artificially enhanced outcomes rather than competing in a fair way. This is a sign that the model needs reworking - hopefully this is considered in the design of the revamped guild system when it arrives.
