Pay $1 or more:
Darksiders + Soundtrack included.
Red Faction: Armageddon + Soundtrack and Path to War DLC.
Beat the average:
Darksiders II + Soundtrack.
Red Faction: Guerrilla
Probably a good deal for Darksiders 2 alone. But honestly, with all the THQ sales before, who doesn't have the other three games at this point.
