Back in the day, it was very common for developers to promote the size of their open-world games, but this generation, it feels like the race has finally slowed down a bit. Instead of sheer scope and map size, more detailed, denser worlds are finally taking the spotlight. As a result, there haven’t been as many truly colossal open-world games built around map size as in the PS4 era, although that doesn’t mean there haven’t been any. With GTA 6 launching this month, we’re about to get the biggest and most detailed open world in Rockstar’s history.
For this list, let’s find out which open-world games on PS5 have the biggest maps so far. A few rules for extra clarity first: only games unavailable on PS4 are listed, we’re comparing seamless maps rather than adding up separate regions, and only traditional open-world games with on-foot gameplay count, so driving and flight simulators are excluded. For our most comprehensive list of the biggest maps regardless of platform or genre, check here.
Very few games have official map measurements, so most figures below are estimates and may not be 100% accurate. Map sizes include both land and water.
Sea of Thieves is actually a last-gen title, but since it never launched on PS4 (it originally released on Xbox One and PC), it’s included here. The first of several seafaring games here, it earns its place because, despite the focus on sailing, there’s on-foot gameplay as well, with explorable islands and underwater areas.
