What playing Maniac Mansion is like

Adventure games focus on exploration, story and puzzle-solving rather than combat. Progress comes from examining your surroundings, collecting items and figuring out how they fit together.

Tip for newcomers: Classic adventure games can be cryptic by modern standards. Take notes, try everything on everything, and save before risky choices.
