A former Rockstar's employee's portfolio confirms the works on GTA 6
A person, who states to be a former R* employee, set a profile on Reddit AMA, i.e. Ask Me Anything, and fans eagerly used the occasion to obtain any information on GTA VI. Obviously the profile and the answers has already been deleted,but on the Internet - likewise in mature - fortunately nothing gets lost.
Some QueenSferryCat states that he worked at Rockstar Games at a position of Junior Artist (with further promotion to Artist), so a person responsible for, e.g., creating a game world, building cities, layout of buildings etc. Below, you'll find a few selected questions relating to R* and future games (including GTA VI)
Question: Is there any information/leak that you shouldn't tell?
Answer: Frankly speaking, when I left the company, they never stated to me what details were to be kept quiet. However, due to an agreement I signed back in 2016 all I can say is that 2 games were being worked on during the development of RDR II (already after the GTA V premiere)
Question: Are there any leaks, already kmown, that we can say they're credible?
Answer: The leaks you'll find HERE, are surprisingly close to the truth.
Question: Will the GTA VI action be set in these days? Or, will it be the comeback to the past?
Answer: Definitely they will be current years. R* to some extent is trying to link the newest GTA version with GTA Online. Of course, the campaign for single player still remains the priority and the studio will at all costs try to create an unforgettable history, but the success of GTA Online makes it that the multiplayer in a way indicates the direction in the creation of the new version. Apparently, during the first 3 months from GTA VI premiere, we'll be able to transfer the character from GTA Online to “GTA Online 2”.
Question: Do you have any info on Bully 2? Will Bully 2 be the next game (after RDR II) relased by R*?
Answer: Unfortunately I'd never heard anything about the sequel of Bully, but I didn't have access to all information. Maybe Rockstar Toront is working on the title.
