In Seven Wonders, the blue cards are civic structures like aqueducts and temples. They do nothing during the game but are worth victory points at the end, like victory point cards in Dominion. The red cards are military structures. At the end of each era, players compare how many “shields” of military power they and their neighbors have, and victory points are awarded accordingly (simulating battles). You see the same dynamic that you see in Civilization, where aggressive players go for red cards and compete, while others hoard blue and green (science) cards in self-contained path.
You can build a functionally identical system but change player behavior by changing the flavor text. Keep the mechanics the same but flip the names: that barracks is now a theater that produces “scrolls,” and at the end of each era players compare how much cultural influence they and their neighbors have, and victory points are awarded accordingly (simulating immigration). The former civic structure cards now all have military names, and military prowess does nothing during the game but is worth victory points at the end (which is just as coherent as having aqueducts and courthouses do nothing during the game while they could be given a mechanic showing that they promote health and justice). Better yet, let’s do a three-way trade: now science works like the civics cards did (points per scientific discovery at the end of the game) but the military works like science did; the symbols are now archery, infantry, and cavalry, and you get points for either or both of having one really strong or a complete set of combined forces.
In all those cases, the mechanics are identical. We are just changing names and colors on the cards. But I’m willing to bet that warmongers will still accumulate legions of infantry in that last example, while more peaceful players like me will gleefully compete with their neighbors culturally. It is what I loved about Civilization IV: using cultural imperialism to have enemy cities riot until they could join my empire. You can see the same thing in modded games: take the necromancer, have it summon unicorns and rainbow friendship friends instead of ghosts and demonic worms, and suddenly you have a whole new class that appeals to a different demographic. Tanto Cuore is Dominion re-skinned as a game about Japanese maids, which made it an instant must-buy for one of my friends but drove away other friends who are happy to play Dominion.
