GTA VI vs GTA 6: Is There Any Difference?

The two names get used interchangeably everywhere — here's which one is actually official, and why the other one took over anyway.
There's no difference between GTA VI and GTA 6 — they're the same game, just written two different ways. This comes up often enough that it's worth settling clearly.
Rockstar's Official Naming
Rockstar's official title is Grand Theft Auto VI, using the Roman numeral, matching the branding convention the series has used since Grand Theft Auto III. Every mainline numbered entry has used Roman numerals in official title cards and marketing: III, IV, V, and now VI.
Why "GTA 6" Is Everywhere Anyway
"GTA 6" is simply the common, searchable shorthand fans and media use in everyday conversation, headlines, and search queries. It's easier to type, easier to say, and matches how people actually search for the game online — which is exactly why you'll see both spellings used interchangeably across news coverage, retailer listings, and social media, even though Rockstar's own branding sticks to the Roman numeral.
Does This Affect Anything Practical?
No. Pre-order listings, store pages, and marketing sometimes mix both formats depending on the platform's style conventions, but they all point to the identical release. There's no separate edition, version, or product hiding behind one name versus the other.
FAQ

Conclusion
