The basic resource in Tribal Stage is food, which can be collected by having your tribe members harvest fruit from trees or hunt nearby animals for meat or if you go fishing, provided you have the technology. Food lets you recruit new tribe members; let’s say one of your guys gets killed by a wild animal. It also lets you construct new buildings, and these buildings can help outfit your tribal members with different types of weapons or musical instruments. Finally, food can be used as a gift to help buy friends.
