We'll probably never be able to realize our vision for a video game based on a crime syndicate that operates solely out of subaquatic tunnels. However, Amazon's offering the next best thing: BioShock 2 and Mafia 2 are marked down to $11 and $15, respectively, as the Deal of the Day promotion.

BioShock 2 (PS3 and 360) -- $10.99, down from $19.99
Mafia 2 (PS3 and 360) -- $14.99, down from $29.99

Note: Mafia 2 appears to be the "Director's Cut" released last week, and includes all of the game's downloadable content.
