Database thrillers are a subgenre of knowledge games/thinky games/metroidbranias where the primary mechanic involves searching through databases and other sources for information to solve a mystery. Tumblr user velteris has complied an extensive list of database thrillers and similar games, including The Roottrees Are Dead, Type Help (recently remastered as The Incident at Galley House), and Her Story.
