Yeah. There's some cheap Japanese versions, but the North American releases are terribly over priced.
But I'm sure a reasonably priced one will pop up.
A few months ago there was a hidden stock of games that went up all from the same seller. No one seemed to know about it. I was going to nab the Neutopia games, but I could only shell out for a few. But everyone who bid on the games made out like criminals. hehe. All games were w/card and manual. I think I paid 12 bucks each, give or take, for Dungeon Explorer, Raiden and Galaga 90. No one paid much more than that on the other auctions. Some people only paid 5 bucks for games. lol. Though Neutopia and Neutopia II were a little higher. Closer to 20 bucks. I didn't want to get into a bidding war over it and jack the price up and end up not buying it. I'd rather have the bidder get a good deal.
But just wait around. Those things pop up once in a while.
