Spiel Ultima : Kyouryuu Teikoku

The Worlds of Ultima titles took the Avatar into strange and mysterious places outside the scope of a conventional dungeon-based RPG. This one visits Eodon, an Amazonian world dominated by dinosaurs. There are dozens of characters to interact with, including stone-age tribes, mad scientists and lizardmen. Get ready to fight for survival as gorillas, pterodanodons and tigers encroach. All this is done in a familiar engine somewhere between those used to Ultima VI and Ultima VII
