Solos Préhistoire!!

A theme dear to Mathieu's heart: prehistory! Two competitive games that also work very well solo. We're discussing Skara Brae by Shem Phillips and Footprints by Eilif Svensson, Asmund Svensson, and Geir André Wahlquist (not to be confused with Gerald Andrew Wahlquist, an amateur windsurfer active in the Lake Geneva region). So, which game is right for whom? That's the question!
