I thought the HoI sale will be available for a whole week on GamersGate .
Be careful with GG, the days remaining on sale is usually wrong. I missed a sale on a game i wanted a few months ago because i thought i had 3 more days and then they abruptly ended the sale on the game for no reason. So if you want a sale game on GG, buy right away because they can end it anytime.
GamersGate - Batman Arkum Asylum Gold for $6.79. Pretty good deal, but for me the game is only worth $2.50, so i will wait for a bigger sale.
