At the clearance rack at Target today, I saw
Kane & Lynch: Dead Men
Tabula Rasa
TimeShift
Two Worlds
for $12.50 each. Yeah, nothing spectacular really, but heck for $12.50 a lot of games go from "No thanks" to "Yes please!" for me.
They also had Delaware St. John 3 for $10, if you're into the whole adventure genre thing. I've never played any of the Delaware St. John games, so you're on your own there.
