I always wanted to try this game when I was a kid. When checking out reviews on Steam I noticed someone mention that Sega was giving it away for free for their 60th anniversary (a few years ago), and that website is still up and running. Long story short, I tried it and it works. Replacing the localhost part of the URL was necessary as the screenshot mentions.
I likely grabbed this game from when it was given away, but its still cool that it is available. Also got a few Steam profile items but never used em.
