This spring, Idea Factory will release Monster Monpiece in North America and Europe. Monster Monpiece is a card-battle game for the PlayStation Vita, which features monster girl cards that players can rub, in order to strip the women of their clothes, in order to power the cards up.

Naturally, the game has an “M” (Mature) ESRB rating in the U.S., but in Europe, it’s rated PEGI 12. Idea Factory explained the cause of the difference in a statement.

“The reason for the difference in these ratings is that Idea Factory International, Inc. chose to opt for a higher age rating for Monster Monpiece,” the publisher’s statement reads. “With PSN-only releases, publishers have the right to rate their own titles; hence, we decided to rate Monster Monpiece Mature due to the sexually explicit images and hand actions performed during the game.”

They elaborate: “However, the PEGI rating is still rated by the PEGI Administrator. With our sufficient material assets for their review, they rated it 12+ because of the minimal amount of violence shown in the game. We appreciate your understanding in these rating differences.”

Monster Monpiece will be available this spring as a download title on the Vita. Certain monster cards have been removed from the game, due to concerns regarding sexual content. You can read more about that here.
