Everyone knows about the gold standards that are Time Crisis II and House of the Dead II

But I would like to bring up Rail Chase 2, only because it's intro and opening track are fucking awesome.

Technically it isn't a light gun game because it uses a joystick (not a mounted swivel gun like in T2 Arcade or Alien3 the Gun, an honest to god regular joystick like Star Wars Trilogy) but I still think it's neat. Perhaps in the modern age of couples shooters, Rail Chase 3 may see the light of day.
