Amusement Makers is the name of a college game development team that worked on several games during the course of their existance. Concerning the Touhou series, they worked on all the early PC-98 games from Highly Responsive to Prayers to Mystic Square (Touhou 1 to 5).

On somewhere between Mystic Square and Embodiment of Scarlet Devil, ZUN separated from the Amusement Makers team (probably due to graduation) and continued work on the Touhou series under the name Team Shanghai Alice. Today, Amusement Makers continues to work their own projects, most notably their "Seihou" (Western) series, which are developed by juniors who's inspired by the "Touhou" (Eastern) series.
(Actually, these juniors are now separated from Amusement Makers too, and releasing their games under the name Syunsatsu Sare Do.)
