On the E3 2013 pre-show stream, Sony announced Destiny of Spirits, a free-to-play RPG for the PlayStation Vita. From the trailer, it seems there will be changing blessings and powers, encouraging you to check in daily. Also, each unit has an elemental power, so expect there to be some strategy around using each elemental to your advantage.
Destiny of Spirits is expected to come out some time later this year.
