What's the holy grails of the SNES? Dracula X and Aero Fighters?
Everdrive.
Super Negroid.
There's a lot of SNES games that are expensive, and considered rare. Hagane, Earthbound,Aerofighters, the blockbuster carts, etc.. You can probably pick any of them up on eBay any day of the week if you have a small fortune to blow.
Wasn't Lady Stalker brought to the US by some guy who was a book lover or something? He liked his games blue rare, I guess...
Super Negroid.
Don't think anyone mentioned the MAC military training game with the gun, and the Miracle Piano game. May have that MAC games name wrong, but I'm sure you all know what I'm talking about.
** Edit **
Looks like that Miracle Piano is a lot cheaper than it use to be. I could have swore it use to be double or triple what it's selling for now.
I guess R-type III is a grail. At least, it's at grail prices these days...
