I can name innumerable Schmups ("Shoot em' Ups". Think Galaga, Gradius III, or R-Type).
Star Fox 64 made the Schmup accessible to most players.
Outside of the "Bullet Hell" series of schmups (which is more like trying to navigate the lines of a Magic Eye painting), I cannot really think of any terribly difficult ones.
Seriously though. R-Type 3 on Advanced Mode (you have to beat the game) can be brutally unfair past stage 3.
