Phantasy Star Portable 2 has all kinds of tie-ups ranging from sensible additions of items from other Sega games to hilarious pizza box shields. These collaborations were designed for Japan and not everything made the cut, but Sega tried. Really.
When Siliconera spoke with Aaron Weber, Community Manger, he told me they actually looked into keeping the bikini pinups from Young Jump. Sega of America couldn’t work out a deal, so they created a contest to replace the models with fan art. The international version will have digital Rappy and Alis Landale (she’s from the original Phantasy Star) posters in the game.
