11. LEGO City Undercover
While a LEGO game may seem an odd choice to put on this list, LEGO City Undercover is one of my favourite open world games on Xbox One. It's a game that's been dubbed "GTA with LEGO" many times, and it's a pretty accurate description. Minus all the sex, drugs and violence, of course.
Playing as minifig cop-slash-everyday hero Chase McCain, there's a whole lot of crime breaking out all over LEGO City and it's up to you to bring peace back to the colourful brick-built world. If you've ever played a Traveller's Tales LEGO game, Undercover will feel instantly familiar to you. It's the traditional LEGO game gameplay we all know and love, but in a fully open world environment.
There's a story to follow, spread across 15 chapters, but outside of that, there's a good 40-60 hours' worth of extra content to sink your teeth into; whether it's taking part in races, finding hidden golden bricks or completing master builds across the city.
It may be a bit 'childish' compared to some of the other entries on this list, but just because your six year old can enjoy playing it with you doesn't make it any less fun. In fact, the family-friendly element only makes it more enjoyable - and it's packed with plenty of humour that even the most fully grown of fully grown adults will get a chuckle out of.
Plus, you can also play it in local co-op. And we all know that things are more fun when shared with others.
10. Saints Row IV
A rather disparate entry from LEGO City Undercover, Saints Row 4 is definitely not family-friendly. I mean, unless you'd be comfortable with your kid running around a digital city, waving around a giant, floppy dildo and beating enemies with it. Thought not.
The latest in the Saints Row series from Volition, 4 is by far the most enjoyable and most polished of the franchise. It's a game purely for folks who don't take themselves too seriously, packed full of irreverent humour, a crazy storyline that involves you playing as The President of the USA (a much better one than Trump, too), and a lot of alien abductions.
If you've played a Saints Row game before, then you know exactly what to expect, complete with the one and only Johnny Gat and the crazy giant cat, Professor Genki. It's packed full of wacky missions to complete, gives you the ability to jump and glide through the air like a superhuman maniac, and will have you chuckling from start to finish. You can't ask for much more than that.
Well, unless you've not got a sense of humour - then you may want to give this one a miss.
Saints Row 4 lets you play online with a friend, too. All story and side missions can be played in online co-op, making the ridiculousness even more crazy. It may be a few years' old by now, having released originally on Xbox 360 back in August 2013, but it's still one of the best open world games out there.
