Tactical RPG Rainbow Moon reminds me of similar but classic titles from days gone by like Shining Force II and Illusion of Gaia -- it's got that same spirit. If you're a fan of those, you'll want to check out the game, which is available as of today on PlayStation Network, and priced at $15 (cheaper if you're a PS Plus member). See what it's all about in the trailer below.
Beyond that I've got yet another developer diary for you. This one focuses on character development, and you can see it below. If you want more, there are others which feature questing and combat, and classes and tactics.
