• Bad Export for You: Life Force (NES) only allows two options per ship, while its Japanese counterpart Salamander (FC) allows three.
  • No Export for You: Much of the series. In fact, in a world where the U.S. North America gets priority over Europe when it comes to video game releases, the opposite applies for not only this series, but the Affectionate Parody, Parodius, as well.
  • Sequel First: Gradius II was released in 1988 in Japan and Europe, but not in North America, where it was officially unreleased until its appearance on Gradius Collection in 2006. Gaiden is a milder example; IV and Galaxies came after it and were released here before Collection (which included Gaiden as well).
  • What Could Have Been: The canceled racing game Vic Viper.
  • Wiki Rule: Yes, it has one.
