It’s been over two years since the initial release of GTA 5. The game is one of the most successful of all time, shipping over 60 million copies across all platforms. But while the multiplayer element continues to receive new content, we still haven’t seen any single-player DLC.

If a report from Techradar proves to be true, the chances of getting any new solo missions are looking even slimmer, as development on GTA 6 has already begun.

The website’s source claims that while preliminary work on the sixth main installment in the long-running series is underway, the game’s location has yet to be decided.

It’s also revealed that Rockstar had planned to create Grand Theft Auto: Tokyo many years ago, and even visited the Japanese capital to assess its potential as a location.

The developer was supposedly “serious” about the idea of taking the franchise to Asia around the time of GTA 3 and Vice City, but Tokyo’s “problematic” road system was allegedly one of the reasons why the plan never became a reality. In 2003, Rockstar filed a trademark for GTA: Tokyo, as well as ones for GTA: Bogota and GTA: Sin City.

Another reason we never got GTA: Tokyo was apparently due to Rockstar’s reluctance to move the series outside of the US. Barring the two 1999 mission packs that were set in London, GTA games have always taken place in fictional cities based on real US locations. The developers worried that moving Grand Theft Auto to another country may have resulted in it feeling less like the GTA titles people know and love.

However, the GTA: Tokyo idea was a long time ago, so there’s every chance that Rockstar could now decide it's time for a change and locate game number six in a new continent. It is, after all, hard to imagine a GTA title being unsuccessful, no matter where it’s set.
