- Bad Export for You: The English version of MARZ loses a LOT of story-related content, "Blind Idiot" Translation, and it has shoddy English voice-overs.
- No Export for You: The Sega Ages 2500 Series Vol. 31: Cyber Troopers Virtual-ON for the PlayStation 2 was released only in Japan, and it's considered the best port of the original game thus far, much to Western fans' dismay.
- Virtual-ON: FORCE for the Xbox 360 is also a Japan-only port of the series' third installment, but thankfully the game is region-free, making the game import-friendly... if you're willing to spend a lot of money for it (depending where you're importing it from), especially the rare MEMORIAL BOX 15 premium package.
- Operation Moongate's Model2 Collection re-release on Xbox Live Arcade and PlayStation Network is also Japan-only, which has HD graphics surperior to the Sega Ages 2500 Series version on PlayStation 2. Needless to say, some people are pissed about this.
- The PlayStation Network re-release of MARZ also got this end of the stick. Thankfully for those with Japanese PSN account and access to Japanese currency can play MARZ without the laughably bad voice-overs and removed content from the English version.
- This was nearly the case with the Dreamcast version of Oratorio Tangram, as Sega had no plans to release it outside Japan at the time. However, Activision stepped in and published the game in North America, although the network feature was removed and the game didn't see a release in Europe.
- Portmanteau Series Nickname: "Oratan" by the fans of Virtual-ON: Oratorio Tangram.
- Rule34 — Creator Reactions: Because of this, Kotoki himself indulges with rather fanservicey female Virtuaroids. One example being the Playboy Bunny versions of Fei-Yen Kn and Angelan from Oratorio Tangram.
- Sequel First: If you live in Japan and have an Xbox 360. Oratorio Tangram Ver.5.66, the game's first sequel, was re-released in 2009 world-wide; Operation Moongate's Model2 Collection Japan-only re-release showed up February 13th, 2013.
