I know that maintaining such a big database of classic games you have prevents you from expanding that database with other (or all) genres right now. But I would like to share an idea with you regarding user uploads that don't fit into the adventure/shooter and related genres.
Some users (including me) have uploaded many titles on the public or closed sections of the forum which don't fit into the currently maintained Legends World genres, yet they are very useful and/or interesting for a retro PC gaming fan like me. But browsing through the many various topics other users created is a very time-consuming act. If one doesn't have many patience to browse through the user uploads carefully, many hidden gems will be lost forever. So I think you should create a download listing for other game genres which don't receive their own download and description section on Legends World. This section would differ from the regular game pages on the site in that you won't look for any kind of description or screenshots of the games, you just list the games with their name, genre, upload type (iso, rip, etc.), uploader's name and download links (and maybe a small comment from the uploader if he/she would like to say anything about the upload). A single-page site with a table where every game entry is just a single line (or two if there's comments). I think it wouldn't consume too much time to achieve and all users would really benefit from it. If the users want to get infos about any release they can look after them on Google. And if you want to expand your database with new genres you'll already have a small list of uploads in that genre. You can also restrict the acces this list for uploaders only, if you don't want to share it with the public.
I really look forward to your reply, to see if it's a good idea. Many thanks for considering my request.
