PlayAsia seems to have a couple of good deals this week, just nice for Christmas..
Prototype 2 for PS3 (US $16.90) - Buy Prototype 2 (PS3) (Affiliate link)
and Hitman: Absolution for XBox 360 (US $19.90) - Buy Hitman: Absolution (Xbox360) (Affiliate link)
Albeit both are Korean versions, but if you don't mind that, they are both awesome deals.
Uncharted 3 for PS3 (US $17.90) - Buy Uncharted 3: Drake's Deception (PS3) (Affiliate link)
This one is the US version. Also a very good deal for one of the best PS3 games out there, or so I hear (Never played the Uncharted series, hehe!)
Pretty good deals and will be a good time to get these if you have been eyeing these games. I'll be grateful if you can use my affiliate links if you decide to buy ;)
