Sapiens is an action-adventure and text-based game set in an open world environment and played alternatively in flip-screen and first-person perspective.

Myriad Online, the company created by the Guillion brothers, published a Mac OS and Microsoft Windows port in 1996, recompiled in 2017.

The RPG aspect also entails customizing five parameters at game start (agility, strength, charisma, vitality, resistance), while gender defines different aptitudes.

The game plot, influenced by J.-H. Rosny aîné's writings as well as The Quest for Fire, features several missions and reaches a climax when the player takes the lead of its tribe.

When hungry, they must eat proteinic food in order to avoid starvation; when tired, they must sleep, and when they wake up, they will be thirsty, and hence must reach a water stream to quench their thrist and they can fill their wineskins if available in their inventory.
