The Sims 2: Castaways (wii)
The word sims is what really scares people off. It has the sims but there needs are easy to meet. The sims don't have jobs they have to go in this game, they don't money so you collect resources and the craft with them more like an rts. You can make tools, clothes(your clothes degrade over time and slowly provide you less comfort and look sexy

), furniture, houses. You can build all your house(or build one of the games preloaded ones). Houses wear down over time(tiki falls apart faster then say wood) and you can build almost anywhere. You might want to build near the shore so you can fish or near a hotspring so you can get a really nice bath as you go more places are found. It has changes in weather. The food system they use is great, there are tons of diffrent foods u can pick/catch/find. You can grow your own gardens. There's a story your following about trying to get home but you can keep playing after. Oh and MONKEY BUTLERS! For the sake of this game I have come up with a few alternate titles.
