Karl Roelofs

On March 7, 2012, Karl Roelofs co-founded Zojoi, LLC with Dave Marsh. They had reacquired the rights to the ICOM Simulations properties which included the rights to Shadowgate, Uninvited, and Déjà Vu I and II and materials such as the master recordings for the Sherlock Holmes: Consulting Detective games.

Despite the unsuccessful Kickstarter campaign, Karl and Dave were able to obtain funding through other means for the Sherlock Holmes: Consulting Detective mysteries. The first three mysteries were released on September 18, 2012 over iTunes for the iPad 2 and newer models, and on October 7, 2012 over Desura for Windows and OS X. Karl and Dave took their experience with the campaign for Sherlock Holmes: Consulting Detective and applied what they had learned for their next Kickstarter campaign for Shadowgate. Instrumental to this was that Shadowgate would be re-imagined and that it be in pre-production so that they could clearly communicate their vision through visuals, audio, and art.

On October 26, 2012, the Kickstarter campaign for Shadowgate went live with Karl Roelofs appearing beside Dave Marsh in the campaign pitch video. It had a funding goal of $120,000 and was set to last for 31 days. The campaign was successful and raised $137,232 in pledges by November 25, 2012. With that funding, the new re-imagined Shadowgate moved into production. If the reception to the new revision of Shadowgate is great enough, Karl and Dave have expressed an interest in developing their original vision for the sequel, Beyond Shadowgate, as well as bringing back re-imagined versions of Uninvited and Déjà Vu I and II .

In addition to his video game credits, Karl Roelofs is also the inventor of a published patent for a gaming machine and method. The patent describes a game play mechanism for gaming machines wherein certain icons obtained from the spinning reels could be saved in a separate grid, and then called back in blank areas of the reel in order to complete a winning combination. Karl created this patent while he was working at Video Gaming Technologies. It was applied for on February 1, 2008 and was granted by the US patent office on January 17, 2012.

In 1993, ICOM Simulations was purchased by Viacom, Inc. and renamed to "Viacom New Media". Karl began to work on games based on MTV and Nickelodeon properties, such as Nickelodeon GUTS and Rocko's Modern Life: Spunky's Dangerous Day. After Viacom shut down Viacom New Media in 1998, Karl Roelofs went on to work for brief stints at Konami of America and Kesmai Studios/Electronic Arts. A highlight of this period was his involvement in an online version of the Settlers of Catan for MSN Zone.

Karl Roelofs began his career in video game development in 1985 when his best friend Dave Marsh enlisted him to help with designing a video game for ICOM Simulations. Karl had wanted to be a writer and saw an opportunity in Dave's offer. He accepted the chance to design and write a fantasy adventure game and began working with Dave to create their first game together which would later be called Shadowgate. Karl was hired at ICOM Simulations in 1987 after the company had already released its first two MacVenture games, Déjà Vu: A Nightmare Comes True, Uninvited, and while working on and finishing Shadowgate.
