Others collects games built on engines outside the main categories: custom in-house engines, GameMaker, Construct, older or niche tools, and projects where the engine is not clearly identified. The variety is wide, so requirements differ from game to game.
Read each listing's installation notes, since some of these games need extra runtimes, specific launchers or particular folder layouts. Screenshots and the developer's own documentation are your best guides to what a project involves. If something fails to run, the developer page is usually the fastest route to a fix. LustFever keeps listings on the latest version and links to the developer.
