Bumped into this auction when I was trying to determine the current value of the illusion series games, did a little reasearch and found out it's kind of rare. It's a Majesco rerelease in the same vein as the cardboard Sonic 2.
I have no reason nor motive to nab it myself as I literally just got a lot with both Genesis Illusion games CiB (case versions) among a few other titles a few days ago, so if there's any SEGA collectors that like to collect different releases, well, here ya go.
