I purchased last night these two games for a very very cheap prize at Target.
Yeap, the GH: World Tour was 12.48 (Reg. 49.99) and the GOW: Chains of Olympus 13.98 (Reg. 19.99)
Kind of hard to believe that the PSP game was more expensive than the Xbox game.
Tried both last night and I was really impresed with the GOW graphics for the PSP.
