Perfect Cherry Blossom (InstanceTopic, 17)
From Compile Worlds
Perfect Cherry Blossom is the second game in the Windows Touhou series (making it the seventh overall). Unfortunately, it's far from a successor to Embodiment of Scarlet Devil, as all it really does is introduce an insane amount of new characters and completely nerf the difficulty by increasing the death margin to about a whole second. Oh, and all the music is pretty much half-assed remixes from EoSD too. It's no surprise that the best track in this game is the 5th boss, almost exactly the same as the last game's.
Somehow, despite how much of a lame rip-off it is, it's considered by many to be THE Touhou game, while EoSD goes widely ignored.
