2. The Witcher 3: Wild Hunt
Whether it be Geralt's gruff and manly tones or Ciri's, well, Ciri-ness, whoever you are, there's a good reason to play The Witcher 3. It's a truly massive experience – and not one to embark on lightly. As far as open worlds go, The Witcher 3 takes the biscuit in terms of size and scope – it's apparently thirty times larger than the previous Witcher games. Unless you have a couple hundred hours to spare, you won't be getting far any time soon!
The Witcher 3 follows said gruff and manly Geralt, a monster hunter who sets out to find his adoptive daughter who's being pursued by a group known as the 'Wild Hunt'. It's massive, it's beautiful — even more so now, thanks to the Xbox One X patch — and it's without a doubt one of the best open world games available on Xbox One. Expect a lot of combat, a lot of horseriding, and a lot of sitting around in taverns trying your hand at Gwent.
1. Assassin's Creed Origins
The best open world game on Xbox One is also the newest one on the list. The latest addition to the Assassin's Creed series, Origins, is absolutely spectacular in just about every way, and if you're a fan of open world adventures, this really ought to be top of your wish list.
Playing as Bayek, a protector of his city, Assassin's Creed Origins takes us back 2,000 years to Ancient Egypt — a time where pharaohs still rule the land and Julius Caesar and his Roman armies threaten to take control. A man of the people, Bayek spends his days helping others, along with seeking revenge on the group of men who wronged him. It's an epic journey that covers one of the biggest open world maps we've ever seen — it might even rival The Witcher 3 in terms of sheer land mass — and some of the most impressive landmarks.
From awe-inspiring coliseums to the majestic pyramids, there is so much to see and do in Origins. No two areas of the game feel similar, with so much variation in terms of cities, villages, mountain ranges, and vast oceans. About 60 hours later, I've still got so much more side content to do and locations to see, and I'm not getting tired of it any time soon.
As far as the best open world games on Xbox One go, it's going to be hard to beat Assassin's Creed Origins.
