Here are guides I’ve created to help people check out games, usually older ones, that help provide context for what makes them interesting, what version of the game they should play, any recommended source ports or patches, gameplay tips to help people start playing them, and recommended walkthroughs for adventure games. They are just to help people get started and do not feature any spoilers.
