Amazon takes up to 93% off a selection of video game downloads for Windows and Mac during its Digital Games Mayhem Sale. (The banner suggests discounts of up to 80% off, but we found steeper markdowns.) That's the best discount we've seen on video game downloads from Amazon since last fall, when we saw up to 92% off with a $5 credit. Deal ends May 31. Notables:

• Bastion for Windows for $3.75
• Bioshock Dual Pack for Windows for $4.99
• The Crazy Action Pack for Windows (pictured) for $9.99
• Batman Arkham GOTY Pack for Windows for $11.49
