I know this was mentioned in some previous posts that The Dark Spire for DS is $4.99 at Gamestop. I wound up getting a copy at the Menlo Park Mall in Edison NJ on Friday night. Great part about it is that it was a new copy. I brought the shelf copy to the desk and he pulls out a brand new one from the drawer. It comes with the Music CD and Box and was still shrink wrapped from the factory.
I figured it was a good deal. I heard some good things about the game as well.
Thought I would throw that out there so if you want to pick this game up for cheap I would try the stores as the website doesn't have it in stock.
