Too late to comment, but I wanted to add puzzle games like Portal or The Talos Principle. The world building is stimulant, and the mechanics can be really hard on your first play. Their downside is the rapidly diminishing replay value, unless you collect achievements, which defeats the purpose of a casual game.

When I replay one of those, I do it for the story, because the puzzles are child's play when you know the solutions.
