Open-world games are arguably the absolute kings of the gaming landscape. You get dropped into massive maps with the total freedom to decide where to go and what to do next. Most of these worlds offer hundreds of hours of content packed with side quests, collectibles, and hidden secrets. Back in the day, you had to pay full price for these massive AAA titles, but today, some of the absolute best open-world bangers are super budget-friendly.

Massive Open Worlds

Thanks to Allkeyshop and massive sales, you can now grab huge AAA open-world games for just a fraction of their original Steam price. Even though some of these titles are a few years old, they still deliver gigantic maps and insane playtime. Here are the top 5 massive open-world games you can grab for cheap right now. We’ve got a sweet mix of pirate adventures, fantasy RPGs, sci-fi, and more—so there’s 100% something here for your backlog.

#1: Assassin’s Creed IV Black Flag – Pirate Adventure and a Massive Caribbean Open World

Kicking things off is a true 2013 classic: Assassin’s Creed IV Black Flag. In this entry, you step into the boots of the pirate Edward Kenway. The game throws you straight into the Caribbean, offering a sprawling open world full of islands and cities you can explore with your own ship. You’ll drop anchor in iconic locations like Havana, Nassau, and Kingston. Sail wherever you want, discover hidden islands, loot shipwrecks, and dig up buried treasure. Every zone is also packed with collectibles to easily sink hours into.

Naval battles are the absolute core of the gameplay. You can blast enemy ships with your cannons and board them with your cutlass drawn. Your ship, the Jackdaw, can be fully upgraded with new weapons using the loot you pirate on the high seas. Throw in side quests, treasure maps, and hunting, and you’ve got endless content. It’s the perfect blend of classic Assassin’s Creed parkour, exploration, and pirate gameplay. And like every game on this list, you can snag it for practically nothing right now.

#2: The Witcher 3 Wild Hunt – Story-Rich Fantasy RPG with a Gigantic Map

Next up is the undisputed GOAT of open-world RPGs: The Witcher 3 Wild Hunt. You play as Geralt of Rivia, a monster-hunting Witcher. The game features a breathtaking open world divided into several war-torn regions. You’ll explore the gritty swamps of Velen, the massive city of Novigrad, and the harsh Skellige Isles—each with their own distinct vibes, towns, and deadly beasts. The world feels incredibly alive thanks to its NPCs and dynamic events.

The Witcher is heavily praised for its top-tier side quests; even the smallest fetch quest usually unravels a crazy story. Monster hunting with your silver sword is your bread and butter (steel is for humans). You can craft armor, brew potions, and level up your Witcher Signs. The Hearts of Stone and Blood and Wine expansions make the map even more massive, making the heavily discounted The Witcher 3 Complete Edition an absolute steal. Be prepared to easily sink over 100 hours into this masterpiece.

#3: Hogwarts Legacy – Magical Sandbox Around Hogwarts and the Highlands

Hogwarts Legacy is the action-RPG every Potterhead has been waiting for. You start at Hogwarts in the 19th century, way before the boy who lived was even born. The game hands you a massive open world covering the castle and the surrounding Highlands. You’ll check out iconic spots like the classrooms, the village of Hogsmeade, and even brave the Forbidden Forest. Beyond that, there are tons of small hamlets, ruins, and caves filled with magical beasts to discover.

To get around quickly, you can hop on your broom or ride a magical flying beast. The Hogwarts castle is fully explorable, and attending classes actually teaches you useful spells. The place is packed with secrets, puzzles, dungeons, and mass amounts of collectibles. You can even rescue magical creatures and raise them in your own Room of Requirement. It strikes the perfect balance between a compelling story and total open-world freedom.

#4: Horizon Zero Dawn – Post-Apocalyptic World Ruled by Machines

Horizon Zero Dawn is a killer sci-fi RPG from Guerrilla Games. The game drops you into a post-apocalyptic future where massive mechanical dinosaurs have taken back nature. You play as Aloy, a fearless outcast and hunter. The map is stunning, featuring lush forests, snowy peaks, deserts, and the overgrown ruins of old human cities. The contrast between wild nature and high-tech machines is unique. Horizon features a deeply emotional story that pushes Aloy to travel across the entire map, facing increasingly deadly machines.

Aloy primarily fights with her bow and elemental traps. Every machine has specific weak points that you need to scan and tactically shoot off. The map is loaded with side quests, bandit camps, and challenging hunting trials. Hidden lore and collectibles constantly reward exploration. The new Remastered Edition polishes up the graphics and packs in all the DLC. The Frozen Wilds expansion even adds a massive new snowy region. Visually and atmospherically, it’s an absolute masterpiece.

#5: Just Cause 3 – Pure Chaotic Sandbox Destruction on a Mediterranean Island

To wrap things up with a bang: Just Cause 3 is the pure definition of sandbox action. The game drops you onto the fictional Mediterranean island of Medici, run by the insane dictator Di Ravello. As rebel Rico Rodriguez, your job is to overthrow the regime. The map is unbelievably massive, packed with mountains, small towns, and heavily guarded military bases. You are basically just there to cause absolute chaos. Armed with Rico’s grappling hook, parachute, and wingsuit, you traverse the sky at breakneck speeds.

The gameplay? Pure destruction. You can blow up red gas tanks, satellite dishes, military bases, and even bridges. Liberate settlements by blowing the dictator’s propaganda to pieces. You have access to endless vehicles—from fighter jets and attack helicopters to tanks and sports cars. The physics engine lets you pull off absurd, action-movie stunts. Do yourself a favor and grab the XXL Edition on sale: it gives you a jetpack wingsuit and even crazier weapons for total mayhem.
