I wanted to get a list of Halloween themed games. I always enjoy playing these types of games throughout the year as it gives me a little Halloween feeling all year long. Off the top of my head:
Ghost N Goblins (NES)
Super Ghouls N Ghost (SNES)
Hill Climb Racing (Haunted Stage on Android) This has some great Halloween music.
It doesnt have to be a Halloween game just games that have a aspect to it that reminds you of Halloween.
