What's in a Theme?

How much does the theme really matter in a game? Short answer is it depends on the game.

The theme really matters when the game is built around the game. In this case the game is theme dependent. If the theme is a secondary characteristic that can be swapped out with another and the game still works as is, then the theme does not matter as much.

Examples.
1. Dominion. It's medieval theme is really independent of the game play. In this case the them doesn't matter as much whether it's medieval or pirates.

2. Agricola. It's farming them is so intwined with the game, that if you switched the theme to pirates, it wouldn't work.

3. Vinci/ Small World. As evident by the updated version, Vinci/ Small World can transcend its theme reality/ fantasy war game.

4. TV Wars. Again another game, where if you change the theme to say pirates, the game play would fall apart.

5. St. Petersburg. This game, although theme oriented, is not theme dependent.

6. Vinhos. Wine making just would not work as a pirate game. (What pirates are awesome!) ... Even if it was a pirate rum-making game.

Furthermore, a game that is built around a theme must be more detail-oriented towards the theme. Example: If you're playing a French game, the money should Francs or Euros, not Dollars. The game should also feature uniquely French things like the Eiffel Tower, wine, French phrases, etc.
