Has anyone ever started a project to list game systems, RPG settings, modules, etc. by setting? The overwhelming majority of products have been lumped into very broad genres: Fantasy (i.e. Medieval Europe... actually Anglo-Frankish Europe), Sci-Fi (which may as well be called the Asimov-Clarke-Heinlein universe), Cyberpunk (Blade Runner), Horror (Gothic), etc. I like to take historical themes and settings and weave them together, but it requires a lot of browsing through published material new and old. So if I want to find published material on, say... nautical themes, in a medieval setting, and pan-Mediterranean culture, wouldn't it be nice if there were a searchable/filterable database or wiki that classified RPG products by publisher, game system, genre, setting (historical), setting (fictional), and theme?
