Similarity map

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

  • Purple star: this page’s game — everything on the map is relative to it.
  • Coloured chips: click to highlight games that mainly differ on that motivation; click again to reset.
  • Dotted line: link between this page’s game and the one selected for comparison.
  • Hover a dot to preview that game in the panel on the right; click to keep that comparison.
  • 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 (hidden on purpose).
