With Thanksgiving just a week away in the US, several Mac game publishers already are dropping the prices on their Mac App Store titles in celebration. We're talking some steep discounts on some triple-A games, including:

• Galaxy on Fire 2 Full HD on sale for $9.99, down from $19.99.
• Bastion on sale for $6.99, down from $14.99.
• Tomb Raider: Underworld on sale for $9.99, down from $24.99.
• Star Wars: Knights of the Old Republic on sale for $4.99, down from $19.99.
• Call of Duty 4: Modern Warfare on sale for $7.99, down from $29.99.
• BioShock 2 on sale for $11.99, down from $24.99.

These are all great titles that we can recommend without hesitation. If there's a particular game you've had your eye on but don't see here, make sure to check the Mac App Store to find out if it's also on sale, since chances are it very well could be.
