Woah. $94 USD or AUD? I love the game, it can get quite challenging which is good. It was developed by SegaWOW, which is a combination of WOW entertainment (House of the Dead) and the awesome Overworks (Streets of Rage, Skies of Arcadia, Phantasy Star, etc.) It feels like a combination of Fire Emblem and a light shooter.
I hear the sales didn't do to well compared to big hitters like a couple million in the first 24 hours, but it did sell a respectable 200k in Japan, so I hear?
