"What are Blisterpack games?"
is harder to answer since it's harder to even find eBay auctions of
Mega CD games in Blisterpacks than Mega CD games sealed or with the
spine card combined! In France, some stock of Mega CD titles came in
sealed contained in a Blisterpack so it was easier to keep stock in
desplay, hung up on a hook so people can pick out a game and bring it
to the counter. From the images of Blisterpack games found, it seems almost every Mega CD title was released in this form. However, games with Black Spines (post-1993) had different artwork on the Blister Package itself.
