- Marth Debuted in "Smash Bros.": Western players of Acceleration of SUGURI X-Edition likely became aware of the existence of QP's own series due to her guest appearance as one of the game's final bosses and unlockable characters.
- No Export for You: While the sequel and the Xmas Shooting - SCRAMBLE!! remake averted this thanks to Fruitbat Factory localizing these games overseas, their predecessors however are still Japan-only and have not seen an English localization, official or otherwise. This however may likely be due to the poor compatibility these games unfortunately on modern Windows operating systems without certain DirectX wrappers and lack of interest of translating/bug fixing these games.
