Aion Introduces Faction Incentives
NCSoft, developers behind Aion, recognize that there is a substantial imbalance between the Elyos and Asmodian factions on a number of servers. To remedy this imbalance, they are offering incentives to the Asmodian side - ramped up rewards earned via leveling.
This incentive system is only part of a full solution - while it does generate increased interest in playing the less-popular faction for the rewards, it doesn't force those players to take part in the in-game politics and engage in the kind of behavior that builds proper balance. And these new "incentivized" players may not reach end-game, where the imbalance is most apparent, for a long time. However, it is a step in the right direction.
