In the wake of last month's Ultimate Electronics (formerly Audio King) 50% off PS2 sale (Don't know if it's still going on- checking today), last Fri at CompUSA they had a big bin & table of discount games- most were $15:
WarHammer 40K: Fire Warrior (PS2)
Gladiator: SoV (PS2)
Aggressive Inline Skating(? PS2)
Eternal Darkness (GC)
were some. Had Xbox titles too but I didnt pay attention to them.
