Originally released on the PlayStation in 2000 as Infinity, Never7 is the first game in the Infinity series. A port (of sorts) containing exclusively new routes was released on the Neo Geo Pocket Color as Infinity Cure. The most well-known version, titled Never7: The End of Infinity, was then released on the Dreamcast; it integrated all routes of both previous releases into one, added new voice acting, and added an "Append Story" system, where players were free to use the game's assets to create their own scenarios and then upload them for other players to play. It was later released on a variety of platforms. In 2010, an English fan translation of Never7 was released. Finally, Never7 recieved an official "remaster" in 2025 along with Ever17. This remaster was heavily criticized for poor translation, AI upscaling of the original assets rather than redrawing them, and the cropping of 4:3 assets to 16:9.
The most widely recommended way to play Never7 nowadays is Never7 Eternal Edition, created by Malucart. It contains much more carefully upscaled assets as well as a whole host of quality of life features that no other version of the game has. You will need the LOVE engine to run it.
Infinity Museum is a companion disc to the original release of Infinity made for Windows. It could be purchased from KID directly and contained an HTML gallery of music and images from the games, screensavers, concept art, and a demo of the upcoming Never7 release for the Dreamcast. In the interest of preservation, I have left the HTML gallery completely unmodified, which includes not adding a link back to the rest of the website. If you want the entire contents of the disc for yourself, you can download it here.
A more comprehensive retrospective on the game and its first English translation by its translator, John Hooper, can be found here.While it is not an official release, I would be remisce not to mention Never 7: Kurumi Cure. It is nothing short of peak fiction.
