If you like JRPGs, there's a good chance you plan on buying Shin Megami Tensei IV on July 16. There's also a good chance you already own Fire Emblem: Awakening. There's also a good chance you wouldn't mind $30 in eShop credit just for registering both of them with Club Nintendo.
It's a unique cross-promotion between the Atlus and Nintendo series, and an appealing way to make sure fans of either series are hyped for Shin Megami Tensei X Fire Emblem.
Players must register both games by August 31 and complete their respective surveys to nab the $30 in eShop credit. Both retail and digital copies of the games are eligible, but make sure you tie your Club Nintendo account to your 3DS first if you go for the latter.
