Kirby's Return to Dream Land. Spent down most all of my GS points for $25 off of this game. Seemed like a wise decision. I'm not sure why the used value is now back up to retail, but satisfied to have only grazed that bullet.
Apparently it was released so late in the Wii's life that it was a very low production run and there's very little chance of a reprint.
I got lucky and found a copy Saturday night at the Walmart out here in the middle of nowhere for $50. But yeah, Amazon lists it at $80 new $50 used.
The Walmart still has one more copy if someone want's me to snag it for them. Just $50 +shipping for a new & sealed copy.
