The Sims 2: Castaway review at Cubed3.

"The Sims 2 Castaway is the sort of game that you feel total indifference towards. It isn’t hugely offensive, nor is it hugely wonderful, it just bundles along at a steady pace doing nothing to either irritate or annoy. And this, in itself, is dull. The basic premise is simple. You get stuck on an island in the middle of nowhere and you have to survive and stop your Sim from going insane, wetting themselves, collapsing, etc. So all EA have done is move things over to and island and confuse the whole thing by shoving it on the DS."
