I found a copy of Castlevania Harmony of Dissonance at Wal-mart. It was just there by it's lonesome self. Not sure if I'm going to keep it, since it was still listed at $29.82. What say you?
Well, unless you want it for collection/resale purposes, I would pass.
The Castlevania Double Pack had Harmony and Aria of Sorrow on one cart. It can still be found for around $20-30. Check the trading forum if you cant find it at retail.
