The funny thing about Valkyria Chronicles is that its got a shooter type aspect to it. No, its not a twitch shooter but you have to aim and use cover when fighting enemies. I agree with most people here, VC is a great gem in the rough, especially at $30 at Gamestop. If you are uncertain about it though, rent it like I did.
But the next JRPG supposedly is a game called Cross Edge from NIS America. Looks interesting...
