Now, to keep things interesting, scatter a handful of objects across each island and encourage the player to search for them, hidden object-style. But let's not fuss over gathering resources, just allow the player to build, unlocking units as he or she plays.

Let's pretend you have a casual sim game like Virtual Villagers, Westward, or My Tribe.
