Throughout Watch Dogs: Legion, you have two main objectives. The first is to rebuild Dedsec from the ground up after the organization is almost wiped out, and you've also got to bring down the various groups that are threatening to tear London apart, one-by-one.
As you'd expect, it takes a bit of time to achieve all of your goals. Not to mention, there is plenty of side content in the game to keep you busy and distract you from the main mission. So, how long is the game? Using data gathered from HowLongToBeat, here are the average completion times for the game, separated into playstyles.
How Long Does It Take To Beat Watch Dogs: Legion?
Completing The Main Story
If all you want to do is experience the main story, then you'll be in for about an 18-hour playthrough. While you'll witness plenty of great moments in that run, you'll also miss out on a lot. Not only will you bypass some great quests, but you won't have the best operatives in the game on your side. Those who mix in some of the side content during their playthrough end up spending around 31 hours in the game's re-creation of London.
Full Completionist Run
Watch Dogs: Legion doesn't have as much optional content as Dragon Age: Inquisition or a Bethesda RPG.
Yet, a completionist will need to spend much longer with the game than those who are only after the story. To be specific, doing everything in the game takes around 50 - 90 hours, depending on your speed.
How Long Does It Take To Beat Bloodline?
The biggest selling point of the Bloodline expansion is the ability to recruit a few series favorite characters in Aiden Pearce and Wrench. However, even outside of that, it's a strong DLC that includes plenty of content.
If you put all of your focus on completing Bloodline's story, then you'll be done in around 5 hours. Whereas, if you want your money's worth from the expansion and do everything, it'll take you about 12 hours.
