Archaic Sealed Heat, what with E3 right around the corner and a U.S. localization likely, but Play Asia is doing its best to convince us otherwise! The import online shop is selling copies of the gorgeous Mistwalker-developed title for only $11.90 (plus s/h). The deal lasts until next Monday, too, so they're giving us a lot of time to talk ourselves into it.
As far as SRPGs go, you really can't find anything cheaper! Well, unless you pick up Square Enix's iPod-exclusive Song Summoner for $4.99.
