Since the original Nintendo Entertainment System launched in the United States in 1985, video games have been growing at a rapid pace. It seemed as if there was a new gaming system every five years, with each one having better graphics and resolution, a larger hard drive, and higher quality games to choose from.

However, if you compare the differences between an original NES and the latest Xbox One, or PS4, it would not be fair. The consoles of today have grown into powerful weapons of video gaming destruction due to how impressive their engines have become thanks to the advancement in technology.

This has given gaming studios a chance to find new ways to grow their fan base. It is no longer about the resolution, or the story; it is about choices. Gamers today love to play games that allow them to explore an open-world and make their own choices about what they are going to do. The days of linear storylines are long gone. The future of gaming is open-world games.

As video game consoles continue to grow in power and size, so do the worlds that live inside these games. The land areas of some of the games today are massive and it is all thanks to the consoles ability to handle the memory needed to run such a game.

Let's take a look at the 25 largest Open-World games by looking at their size, in square miles.

The Elder Scrolls V: Skyrim (15 miles²)

Upon its release for the console, The Elder Scrolls V, which is best known as just Skyrim, was seen as an amazing work of video game art. The scenery is so beautiful, and high-quality, that you can sometimes find yourself getting actually lost in the forest, for hours, just exploring the vast land area.

The gameplay was built around the size of the map, so there are not many details missing from it. It gives the player a real sense of being in the game even when simply roaming around, looking for a place to build a house. Keep in mind that Skyrim is just a piece of an even larger map.

The Elder Scrolls IV: Oblivion (16 miles²)

As far as open world video games with large gameplay maps are concerned, The Elder Scrolls IV: Oblivion was one of the very first games that truly took advantage of the console it was released on.

Back in 2006, there just was not very many video games that had maps that stretch to nearly 16 square miles while allowing the player a chance to explore the entire map, from inch to inch, and follow a somewhat linear story combined with an array of amazingly complex side stories.

Oblivion will forever be a pioneer in the open world market and it is amazing that it remains in the top 25 nearly 13 years later.

PlayerUnknown's Battleground (24.7 miles²)

The origins of the online multiplayer battle royale phenomena began in 2013 when Brendan Greene developed a mod for ARMA 2/DayZ which was a Battle Royale game inspired by the Japanese cult classic Battle Royale. The film has only been around since 2000, but it has helped to create an entirely new way to enjoy video games.

But when it comes to land size, and area maps, PlayerUnknown's Battleground is the champion with a 24.7 square mile map that allows players to freely explore while looting any weapons or vehicles they can find until there is only one person left standing.

Assassin's Creed Rogue (27.2 miles²)

Due to the nature of the gameplay, Assassin's Creed Rogue has a very large map, about 27.2 square miles, but is not quite the largest in the franchise. The addition of the ship battles have given the Assassin's Creed franchise a reason to expand its gaming area and grow the overall quality of play.

However, because of all their attention to detail, and the ability to upgrade the Morrigan, there need to be some sacrifices or the game would be nearly impossible to run on a console today. That simply means the future of gaming is going to be as bright as the evolution of the gaming console. As they improve, so does the video game.

The Legend of Zelda: Breath of the Wild (28.9 miles²)

There are not very many fan bases that are as dedicated to their game as Zelda fans. Every single time a new Zelda game hits the open market, fans of the franchise quickly grab it and explore. The Legend of Zelda: Breath of the Wild has given those fans a reason for excitement thanks to its very large land area.

The game is so large, the entire map from Skyrim could fit inside of it. The map is nearly 29 square miles, or about the size of Manhattan, New York, and is 100% explorable. In other words, it is not just the map that is large, it is the game. Some games have massive land area maps, but you can only explore a percentage of it. This game allows you to free roam the entire map, corner to corner.

Red Dead Redemption 2 (29 miles²)

The land area of video games are estimated sizes based on various types of measuring and scaling back and forth between other open-world games. Our numbers are not perfect, or exact. They are guesses drawn from various sources and our own measuring.

That brings us to Red Dead Redemption 2, the prequel to the hit video game Red Dead Redemption, and it's impressively large gaming map that many have estimated to be around 29 square miles. That is much smaller than earlier estimates, before the game his the shelves, that claimed that the map was the largest one ever created by Rockstar. But after measuring it, we come closer to the 29 square miles we listed above, which is a couple square miles less than GTA V.

Far Cry 2 (31 miles²)

Although gamers are going to disagree, we have found that the largest game map in the Far Cry franchise belongs to Far Cry 2, with a land size of 31 square miles. The other games in the series come close but are just a few miles short of this one.

To keep things in perspective, if you have the game then take a walk from one end to the other, see how long it takes. It could take close to an hour to walk the entire map, if our measurements are correct, and we believe they most certainly are.

Grand Theft Auto V (31 miles²)

If you are wondering why Rockstar games have found so much success without shoving games in our faces just about every six months, it is because of who they are as a company. They believe in being an original, not a follower. They go out of their way to create a game that can stand alone as a truly unique masterpiece. That is why GTA V is still one of the highest grossing games in the world even after nearly six years since it was released.

The game was built using maps of Los Angeles and Southern California. This helped game designers create a map that covers 31 square miles and includes mountains, skyscrapers, deserts, and an army base that would make even the U.S. Military proud.

Assassin's Creed: Origins (31.6 miles²)

In order to truly test the size of this map, you need to get the game and explore. So, after some rigorous testing, we discovered that the time it takes to get from one end of the map to the other, at roughly three times the normal walking speed, it can take close to 20 minutes in real time. Can you imagine that?

The video game evolution has come full circle now. Open-world games are so large in land size that they take you 20 minutes of real time just to walk across the map. If you do not take on any side missions, or follow the main storyline, it takes nearly 20 minutes to do nothing but walking.

Fallout 4 (43 miles²)

The area map for the hit video game Fallout 4 is 43 square miles. Maybe. Of all the games to make our list, this is the only one that has been debated by gamers from all over the internet.

The outdoor wasteland area is nearly four square miles but that is not the only part of the game that should be considered for square mileage because of how many inside and underground areas are also included. Also, there were a couple of DLC packs that expanded the overall gaming area to reach almost 43 square miles.

Since it is in the game, we decided to go with it and consider it part of the total area size of the map.
