The Legendary Pictures topper has resigned from the board of Brash Entertainment, the videogame publisher he co-founded last year after helping to raise $400 million in private equity funding.
Tull is believed to have been disappointed with the quality of Brash's games, as well as the company's strategic direction. He wasn't available to comment. A Brash rep declined to comment.
It's not clear exactly what changes Tull wanted at the publisher, though possibilities include a stronger focus on quality, even if that meant delaying releases, and abandoning its exclusive focus on licenses.
