One name is Eric Martin. He is the creator of the Animal Herders collectible card game.

Animal Herders is a card game for kids that is similar to Pokemon but much more simple. The cards focus on a picture of either a clay animal or a clay food. Two players build a herd and then battle one herd against another. The more powerful herd wins while skill is used in building the herd strategically and maintaining the herd through the use of food.
