odin sphere, though i'm really kicking myself for not picking up persona 3 instead. don't get me wrong, i love odin sphere. it's just that it's still available at the local stores for 10 dollars cheaper, whereas P3 is now an ebay endeavor for like...30 or 40 bucks over retail.
also i know this has nothing to do with the post topic, but the time i picked up odin sphere i also got yakuza new on BB clearance for 7 bucks. i think playing that game felt sweeter than odin sphere.
