Touhou Project

The Touhou Project (東方Project), also 東方プロジェクト (Touhou Purojekuto) or Project Shrine Maiden, is a Japanese doujin game series that specialises in shoot 'em ups by sole Team Shanghai Alice member ZUN. Generally, it's a series of 2D (with 3D background) vertically-scrolling danmaku shooting games, that also creates related print works and music CDs. There are also seven spinoffs co-produced with Twilight Frontier, called "danmaku action games." The works of Touhou Project are sometimes called the Touhou Series (東方シリーズ Tōhō shirīzu) for convenience. The Guinness World Records named the Touhou Project as the "world's most prolific fan-made shooter series." (Source: Touhou Wiki)
