As far as I know, from what I have read online, Road Rash for the Sega Master System was not a U.S. Release. Over the years I have looked at eBay auctions for it, and seen it go for $40.00+ generally.
Two weeks ago I was perusing auctions for a copy of Road Rash for the Sega CD (I already have a great condition case with artwork and manual for it) and happened across an auction for a Master System loose cartridge for $9.99 with Free Shipping.
There were two others on eBay as well, one complete with a damaged manual for $48.00 and another complete and in good shape, they were asking $74.xx
I Took a shot, and placed a bid on the $9.99 loose cartridge, and waited for the auction to close. I won it for $9.99.
Label is not perfect, but I bought it to play.
Not bad, now my Sega Master system collection is up to 4 games.
Later that day I decided to see if I could find some artwork online for it, and came across another auction for Reprinted artwork and in a Universal game case for $5.3x shipped. Not bad, clicked Buy It Now, and had it a few days later.
Looks Great and for $5.00, works for me!
