>Artan is a fictional continent set in the Atlantic. Players can either join as indigenous peoples (who are created by said players) or as colonizing powers (who are real countries, e.g. England, France, Spain, etc.) The game is turn-based and text-based. Gameplay becomes increasingly complex as the years go by and players are confronted with developing societies. Politics, economics, culture, religion, and pretty much every facet of society are increasingly simulated in some way.

I figure this would be relevant for /christian/ for reasons that shouldn't really need explaining. Players can join as Spanish church officials, a Puritan colony, or all sorts of explicitly religious roles.
