Resource

Resources are introduced in The Sims Castaway Stories. They have replaced Simoleons. There are many ways to get resources:
 * Choping wood.
 * Smashing rocks with an pickaxe.
 * Gathering metal parts.
 * Cutting grass and bamboo.
 * Collecting skeleton bones.
 * Going to work (this also brings food).
 * Selling things.

Trivia

 * When Sims are playing poker they use Resources.
 * When a Sim is tipping a maid or a nanny, he/she's handing money (probably Simoleons) but it says that those are resources.
 * The Recources icon resembles a treasure trunk.
