Thompson's Road 4D. Arguably one of the first horror games that was both educational and horror. The final boss, Red Mouth, was censored in Germany because it was using Riddler in the sprite. The gameplay is mostly a linear game about a ghost train named Stewart who is still alive beyond the grave due to a grudge against the god of trains, Red Mouth. The game is known for several different gameplay types (much like the Sega Saturn game, Mr Bones). It was accidently put inside many schools under the idea that it was a fun game for kids, but it proved to be a problem for many schools. It's pictures of gore, animal corpses, and dead trains proved to be to much for the little kids at school. The game was recalled after they found pictures of a dead mouse in the game files. (Allegedly used as a placeholder for the roadkill seen in the railway segments of the game). This and the fact only 1000 copies were ever produced made it a hard game to track down. So much so that several people claim that it was never made, due to the fact that the alleged publisher, Strokey Interactive, has no record of existing. Some think it was a placeholder on the only picture of the box art and that the real publisher is a different company. The game has never resurfaced since.
