This is a very unique and obscure rpg, its one of those dungeon crawlers where you walk around, encountering enemies, but whats unique about this game is that each floor has randomly placed items, you never know what you're going to pick up. Its kind of like boring rpg but as if it was made into an actual game (thats how i look at it, at least). Its really fun but really hard at the same time, i definitely recommend giving this a go if you're looking for something new to play.

heres example gameplay if you want to see what its like. YouTube - Mystery Dungeon: Shiren the Wanderer review

I believe it was also remade for DS, not sure if it was localized or not.
