Although several developers, Square Enix included, released games based on the Fushigi Dungeon ideas, it has been years since Chunsoft released an installment for the original Fushigi Dungeon Furai no Shiren series. This series is said to be RPGs worth playing a thousand times due to its unique monsters, puzzles and randomly generated dungeons.
During his travels, Shiren is led to the Karakuri mansion by his uncle a.k.a his kendo teacher's mysterious key and together with his partner, a talking ferret, they must solve the mysteries within the dungeons and battle the monsters hidden within.
Aside from the randomly generated dungeons and the older monsters, the system is upgraded to include an array of new elements like an online system that allows you to contact other users via the Wi-Fi network and a variety of new monsters that are based on ancient Japanese myths and traps that controls the flows of battles that even veteran gamers will find challenging.
