Two Worlds, Rise of the Argonauts, and More For Cheap

GoGamer has kicked off another one of their "48 Hour Madness" sales, during which you can score Two Worlds and Rise of the Argonauts (as a bundle) for $4.90 and Trine and The Lord of the Rings Online (as a bundle) for $5.90.

Anybody know if a retail version of Trine can be activated on Steam?
