Abandonware is a popular word, but it is not a magic legal category. In everyday retro gaming language, it usually means an old commercial game that is no longer sold, supported or actively distributed by its rights holder. That definition explains the culture around the term, but it does not automatically make a game free to download.
The confusion comes from a real preservation problem. Many games from the 80s, 90s and early 2000s are unavailable through modern stores. Rights may be split between publishers, developers, estates, brands or defunct companies. Original disks and manuals decay. Players search for a game they remember and find that the official path has vanished.
That absence matters, but absence is not permission. Some old games later return through official re-releases. Some are sold in collections. Some become freeware because the rights holder explicitly says so. Some are open source or public domain. Others remain copyrighted even if nobody can easily buy them. Treating all of these cases as one bucket hides the differences that matter.
This is why VG90 uses an "Abandonware reference" label. It lets the site document a game, show metadata, preserve context and point to the public reference source without hosting files or creating direct download links. A visitor can learn what the game is, when it was released, which platforms it appeared on, and how it fits into gaming history.
For SEO, that label is also useful because people search for abandonware by name, platform and year. A clean reference page can answer those informational searches without pretending that every old game is legally downloadable. Search intent is often historical: "what was this game", "who made it", "what platform was it on", "is there a legal version".
The best retro gaming archives are precise. "Abandonware" may describe a cultural situation, but VG90 separates reference entries from public-domain, freeware, open-source and rights-holder-approved downloads. That distinction keeps the archive useful, searchable and cleaner for everyone.
