The Sims 2: Castaway Tips

Usefull Hints & Tips
The FIRST ISLAND in the game is a really good jungle for getting fruit, and cutting vines. (for building houses, furniture, etc.)

The SECOND ISLAND is filled with food to harvest, so it's a good idea to explore deeply into all the different areas.

The THIRD ISLAND has great fishing if you explore after geyser plains, in the beaches.
