Manhunt 2 (Wii) is $19.99 in the current Microcenter ad. The PSP & PS2 versions are also $19.99. The ad is for the period between 12/3 and 12/16. Manhunt for the PC is also $4.99 in the ad. Prices are also valid online.
Saw Radiata Stories (PS2) at the Cincinnati Mills location for $19.96. It is most likely the same price at all Bigg's locations.
Ninja Gaiden: Black (xbox) was also $19.96.
Star Ocean: Til the End of Time (PS2) was priced at $29.99, new, at Biggs. I saw this price at the Fields Ertel location in Cincinnati and assume it is probably storewide. It is still $49.99 at EB, BB, CC.
