Rockstar primarily developed the game about mafia bosses, vice and and bank robbers, not mentioning Hollywood bosses, over five years from its Edinburgh offices. It walked off with a prestigious Bafta Fellowship and three awards at last night's British Academy Games Awards in London.
The company's co-founder and president Sam Houser, accepting the accolades, said that Rockstar's success was down to the "passion for bringing worlds to life" of its 900-strong team.
"Rockstar is a team and family and it has always been our policy to focus on collaboration," he said.
There were a number of British successes at the event.
