Back in the mid 90's, I always thought titles like Salamander, 1943, Parodius and Twin Bee would eventually become the 'chase rares' for the system. I guess they made so many copies of these games, they became common. All of these titles seem to pop up regularly on ebay for under 45.00 each, except for that one a$$hole in Hong Kong who keeps listing 1943 for 149.99.
