Update: I was unfortunately not aware of Shamus Young's severe criticism of Fallout 3 available here to link in the original piece and I regret that. It dovetails rather nicely with what I've written and it's much better executed than my piece. I strongly recommend anyone...
The objective of the game is to build up a colony with a thriving construction and mining industry, food, tool and weapon production. The player's skillful use of resources, combined with the irrepressible get-up-and-go of the diverse Settler characters, form the foundation for a robust colony. Ensure the settlement becomes more attractive and it could be a paradise, if it weren't for the neighboring races and ...Morbus, with his evil machinations!
The player can decide whether he wishes to lead the Romans, the Vikings or the Mayas. The races differ not only in their appearance and their architecture but also in a variety of details. They raise different farm animals, produce different alcoholic beverages, make and use different weapons and their priests cast unique spells.
All Settlers are actually peace-loving folks, but then there is always that annoying neighbor that occupies the land with those large deposits of gold or sends long-fingered brethren over to swipe your freshly harvested crops. This can cause the industrious Settlers to engage in magnificent battles on land and at sea, battles where the outcome will depend less on the number of troops but more on skillful tactics and well-organized strategy.
