Saboteur got very mixed reviews, was unplayable at release by a large number of people, is available at retail (they have copies in my local JB Hifi for the ridiculous price of $105), and not available on Steam.
As if that weren't already a record number of falsehods in a two sentence paragraph - Steam does the opposite of enslave the customer. It frees the customer from having to pay whatever exorbitant retail price EB games decide to charge, frees the customer from having to worry about losing or damaging the disk, or needing it in the drive, and often frees the customer from the disk-based DRM that many publishers like to force on us.
