50 One of the things I like about Dwarf Fortress is one of the main premises of the game is to create an entire fantasy world, with a complete history fit for a multitude of novels. Civilizations rise, spread, and fall. They wage war on other civilizations, conquering villages and towns and sometimes assimilating the inhabitants into their own culture. In Adventure mode, you can roam around the world, talk to people of all the various races, explore their sites, join in wars, and even hunt down the megabeasts terrorizing the populace. In fortress mode, you take control of a small band of dwarves and guide them through building and maintaining a new fortress, one dwarven site among many. And should your fortress fall to a goblin siege or a terrifying beast of the depths? You can go back in with a new band of dwarves a couple of weeks later and try to take it back. Or maybe you decide that you've gotten tired of managing your fortress and want to move on to something else? Easy- just retire it and pass control back to the dwarves. As time passes and the world evolves, your fortress might succumb to external forces, or it might grow, prosper, and become the new Mountainhome. You could create an adventurer and pay a visit, or start a new fortress somewhere else. You might even get some migrants from your old fortress.
