Leslie Benzies is one of the masterminds behind the GTA series. However, he left the studio back in 2016. He had sued Take-Two Interactive for $150 million in unpaid royalties after he was allegedly trying to be forced out by the company after taking a sabbatical. The claim was settled in 2018.
The year before the lawsuit was settled, he went on to create his own development studio, Build a Rocket Boy. He has brought over many former Rockstar employees that have helped build past GTA titles.
