7 Wonders Duel might be the best two-player card game ever made. The shared card pool creates genuine interaction — every card you take is a card your opponent cannot have, and the visible structure of the three-age decks means you can see the threat coming even if you cannot always stop it. The military and science victory conditions add tension that the original 7 Wonders lacks entirely.

Pantheon adds the gods mechanic, which provides catch-up tools and creates new decision points around the central market. It is a good expansion but Duel is so well-balanced without it that I sometimes prefer the cleaner base game experience. Agora adds a sixth win condition through Senate control and is the more transformative expansion — it adds a third competing priority that makes the game feel more like a negotiation even at two players.

The original 7 Wonders remains excellent at higher player counts for its simultaneity — nobody has downtime. The Duel adaptation understood that two-player games need direct interaction to create tension, and it delivered.
