Sega's 2008 strategy RPG Valkyria Chronicles was received extremely well by critics worldwide.  And though the game wasn't a huge commercial success in the US, it was popular enough in Japan to land itself on the Greatest Hits line up.  The title also spawned an anime series, which just debuted in Japan recently.

Valkyria Chronicles producer Nonaka Ryutaro was recently interview by the Japanese gaming magazine Famitsu Weekly.  He said he was ecstatic that Valkyria was embraced by the Japanese public in the way it was.  Nonaka was excited about the anime's debut, explaining that the anime served as another means to further develop the IP. 

The big news is that Nonaka, in light of the recent popularity, told the magazine that he really wanted to do a sequel to the game, and he was adamant about not leaving the game at just one title.  While it's far from a confirmation, that does bode well for the possibility of a sequel.

Valkyria Chronicles came out in November 2008, exclusively for the PlayStation 3.
