    How to use the graph
    Similar games map

    Each dot is a game. They are arranged from the same motivation profile as in the “Motivations” section below. Closer dots usually mean more similar reasons to play (exploration, competition, relaxation, etc.)—not that one game is “better” than another.

    • Larger dot with a light outline: the game you are viewing.
    • Colour: groups of games with comparable motivation patterns (statistical clusters).
    • Hover a dot to see the game name; click to open its page.
    • Scroll or double-click the chart to zoom out and see more games.

    Why don’t the axes read like a score? This view uses t-SNE: it only keeps who is close to whom. The scales are not “good to bad” or hours played—they separate groups on the map. Read distance between dots, not the axis numbers.
