Dan Houser, co-founder of the studio that gave the world Grand Theft Auto and Red Dead Redemption, will be leaving Rockstar Games by spring this year.

His last day is March 11, according to a form with the U.S. Securities and Exchange Commission filed Tuesday. The form is hosted on Take-Two Interactive’s investor relations site. Houser, who founded Rockstar with his brother Sam, is currently vice president of creative at the New York City-based company.

“After an extended break beginning in the spring of 2019, Dan Houser, Vice President, Creative at Rockstar Games, will be leaving the company,” reads a short statement in the SEC filing. “We are extremely grateful for his contributions.”

A Rockstar spokeperson confirmed the news and declined to comment further, except to clarify that Sam Houser’s role as president in Rockstar, which he founded in 1998, remains unchanged.

The British-born storyteller wrote the landmark Grand Theft Auto series with his brother. Houser’s Grand Theft Auto stories were often biting, critical depictions of modern American culture. Grand Theft Auto 5, the latest entry in the franchise, would go on to become the most financially successful entertainment product — meaning not just video games, but film, music, etc. — in history. Houser is also credited as a lead writer for the critically acclaimed Red Dead Redemption 2.

The Houser brothers were included in TIME Magazine’s 100 most influential people of 2009 list.

“The Housers are doing the world of Tom Wolfe, creating tapestries of modern times as detailed as those of Balzack or Dickens,” wrote Matt Selman, executive producer of “The Simpsons,” for TIME Magazine.
