"The Sims Castaway Stories is the third and final game in the 'The Sims Stories' line of games. The Sims Castaway Stories features the choice of either playing in a story-driven mode titled "Shipwrecked and Single" or a more sandbox "Mami Isle". Gameplay on Mami Island is much more open-ended, enabling gameplay reminiscent of more traditional Sims games." Source: Wikipedia, "The_Sims_Castaway_Stories," available under the CC-BY-SA License.
