I believe the MD version might actually be cheaper. It was when I got it. Awesome game :3
I had picked up a loose NA copy a few months back from a retro shop for. I want to say $14 bucks. I would like a CIB copy and probably should just stop buying loose Genesis games.
But CIB Genesis and SMS games are just getting harder to find and starting to go for a bit more of a premium. Sigh.
