All game developers prototype more products than they ever publish. Usually the prototypes are never published or shown outside and lost completely if the company goes under. The Swedish indie game developer Forgotten Key took a different route and made sure their legacy is not forgotten.
Forgotten Key had a seven year run and published the artistic adventure AER Memories of Old as well as developed designs and prototypes for a number of games. Unfortunately the indie company ran into financial troubles and had to close down. Instead just shutting down instantly and disappearing the developers decided to publish their unpublished, unfinished game prototypes to the wild. This unique act made sure that the company’s legacy is not completely forgotten and lost and might be excellent source material for researchers studying indie development and video game design.
