The Sims 2: Castaway is the third console spin-off of the life simulation video game The Sims 2 for the Wii, Nintendo DS (NDS), PlayStation 2 (PS2) and PlayStation Portable (PSP). It is also available on mobile phones; Nokia offered Castaway on the Ovi Store. A roughly similar game, The Sims Castaway Stories, is available for personal computers, but is not a direct port of Castaway. It is the final game released in the series for both the PS2 and PSP. Unlike most Sims games outside the SimCity branch, the characters do not progress in age in The Sims 2: Castaway. Their hair grows longer and can be cut, but the Sims themselves don't get older. Another significant difference is some of the usually stock features like marriage have been either removed or adjusted for the alternative gameplay style; for example, players have to perform a specific sequence of actions in order for their Sims to get engaged. While this is true in ordinary Sims titles, other titles are more open in their methods of reaching engagement, whereas the process in Castaway is somewhat fixed. Like in The Urbz and later Sims console titles, Sims cannot have children. Additionally, the Nintendo Wii, Nintendo DS and PlayStation 2 versions of the game do not feature WooHoo (euphemistic slang for sexual activities in the series). For unknown reasons, the PlayStation Portable is the only version of the game to feature WooHoo, but only after marriage and specific requirements are met. Additionally, a staple feature in the console games, two player, was not present in this game.
