Wondering how long it takes to complete LEGO Batman: Legacy of the Dark Knight?

In terms of scale, it's probably the biggest LEGO game Traveller's Tales has ever made, mostly thanks to the sheer size of Gotham City.
So, how long does it take to complete the full LOTDK story? Here's what you need to know.
How long is LEGO Batman: Legacy of the Dark Knight? Time to beat explained
LEGO Batman: Legacy of the Dark Knight will take the average player roughly 15 hours to complete.
Based on our time with the game for our review, this assumes that, as well as completing all of the game's story missions, you take some time to explore the side content (and there's a LOT of it) that Gotham City has to offer.
If one was so inclined, you could probably finish the game in as little as 12 hours if you wanted to focus entirely on the story.
If you're thinking about 100% completion, however, things are vastly different.

A completionist run of LEGO Batman: LOTDK requires you to complete every single piece of side content – of which there are hundreds – as well as collecting every Collectible, Suit, Vehicle, Skill and Gadget Upgrade, Batcave Trophy and WayneTech Cache.
Anyone who remembers the infamous Riddler puzzles of the Arkham games will understand the pain here, as to 100% LOTDK you will probably need to spend upwards of 50 hours with the game, with the vast majority of that time being exploring Gotham ticking off these challenges.
Thankfully, most of the achievements are things you'll complete by simply playing through the story, or simple achievements like changing the Batcomputer's screensaver – 30 seconds of work compared to 30 hours for the rest of it!
