Silver Gryphon Games is the creative endeavor of company founders Ben Overmyer and Kevin Rohan. Ben and Kevin have a combined total of 30 years of gaming experience with a wild array of systems, styles, and rules. With experiences ranging from war gaming to diceless systems to traditional board games and CCGs, Ben and Kevin both possess a strong background and familiarity with the gaming industry.


Ben found a copy of Kevin’s RPG Æther in a game shop in the small town of Brookings, South Dakota. Discovering that the creator lived in Brookings, Ben contacted Kevin and the two quickly became friends. At that point, Ben had been working on his own RPG, Ingenium, for a number of years. Eventually, they decided to begin a new game company that centered around both of their creations.

On December 12, 2008, Silver Gryphon Games was born.

Company Philosophy

Operating on the principle that the whole is greater than the sum of its parts, Ben and Kevin use their strengths in tandem and compensate for each other’s weaknesses. The collective effort of the founders allows each of them to focus on their areas of expertise. The result is better products, a more varied product line, and stronger graphics and content.

While Ben and Kevin form the backbone of Silver Gryphon Games, they are constantly on the lookout for new talent that can give fresh life to the gaming industry or experienced hands to leave their familiar touch upon Silver Gryphon Games’ products.
