This game is set in prehistoric central Europe. Most of the animals are accurate with the time, with the exception of Jaguars (Panthera onca) Dholes (Cuon alpinus) and "Sabre-toothed tigers" (assumingly Smilodon populator). None of the three recognized species of Smilodon (S. populator, fatalis, and gracilis) are recorded in Europe, let alone anywhere else outside of North and South America, as are Jaguars. Dholes are only known to have lived in Southeastern Asia (and their historic range is not known to have extended into Europe).
