After an initial delay, Fushigi no Dungeon Furai no Shiren 3: Karakuri Yashiki no Nemuri Hime (Mystery Dungeon Shiren the Wanderer 3: The Sleeping Princess in Karakuri Mansion) will come out in Japan on June 5th. You could casually purchase Shiren 3 after it comes out, but Sega has a tempting offer to attract reservations. If you pre-order the game you are entitled to a 15cm tall Koppa remote control stand.
Speaking of control methods, did you know Shiren 3 supports the classic controller? That is how I got to experience Chunsoft’s dungeon crawler back at Tokyo Game Show.
