Rockstar Games have 'about 45 years worth of ideas' for GTA VI

Posted Feb 3, 2015 by James Walker
Rockstar Games have announced that they already "have some ideas" for the next major installment in the massive gaming franchise Grand Theft Auto. It appears as though GTA VI is beginning to enter early development.

Rockstar president Leslie Benzies explained that although GTA Online and GTA V are remaining the studio's priorities for the time being, some ideas are being played with regarding GTA VI. The game certainly seems to be undergoing extensive consideration internally. Benzies said Where it is going to be set is the first question. Then that defines the missions; you're doing different things in LA than in New York or Miami. The map and story get worked up together, and the story is a basic flow of how it works out so you can layer the missions in.
The game is certainly several years away from any launch though. GTA V has been out for only 18 months. It has arrived on the next-generation Xbox One and PlayStation 4 consoles only recently and its PC gaming debut is still in the future.
The studio hardly needs to rush to meet deadlines or budgets either. Grand Theft Auto V generated $800 million in revenue in its first 24 hours of Xbox 360 and PS3 availability. This negated the $267 million that the company had spent developing the game in just a day.
Rockstar can expect more money to flood in too as PC gamers begin playing GTA V in March. Meanwhile, GTA Online continues to attract attention and updates. In any case, it looks as though GTA VI is very much on the cards though and potentially going into development soon. Whether it will beat the extraordinary performance of its predecessor remains to be seen but Benzies added that the studio has got "about 45 years' worth of ideas we want to do," implying that the scale of the game will be every bit as enormous as GTA V's sprawling world.
