There are a ton ofLEGOgames that have been released over the years with some absolutely ridiculous requirements to 100% complete, mostly because the large amounts of time as opposed to being particularly challenging. If you have the hours to dump into the games on this list and finish them in their entirety, you’ll get some hard-earned bragging rights and will make it into an exclusive club of die-hard LEGO fans. Personally, I gave up on nearly all of these because they were simply way too time-consuming, and some weren’t even particularly fun (looking at youLEGO 2K Drive).
In my opinion, these fiveLEGOgames are easily the most difficult to 100%, with games likeLEGO Star Wars: The Skywalker Sagarequiring upwards of 100 hours, and games likeLEGO Dimensionsrequiring real-world purchases of expensive LEGO sets that unlock in-game characters or levels. Of note: I’m basing these selections on true 100% in-game completion, not necessarily on unlocking all trophies/achievements, which might be a minor distinction, but I feel is an important one. Honorable mentions that didn’t make this list includeLEGO Marvel Super Heroes 2andLEGO Marvel’s Avengers.
5LEGO Star Wars: The Skywalker Saga Has Many Collectibles
Can Take Over 100 Hours To 100% Complete
LEGO Star Wars: The Skywalker Sagais widely praised for its massive scope, excellent gameplay, andhilarious Easter eggs, but completing it to 100% is a serious time-consuming challenge.The game spans all nine Star Wars episodes, featuringover 1,200 collectibleKyber Bricks, 380 characters, dozens of ships, side missions, puzzles, races, and data cards to find. Even experienced players find it difficult to stay organized while tracking everything. One major difficulty comes from the sheer size and openness of the game world. Each planet has multiple zones that are filled with puzzles and hidden secrets.
The user interface, while improved from past LEGO games, doesn’t always make tracking progress intuitive.
Some collectibles are only accessible with specific upgrades or abilities, meaning backtracking is essential. Without a guide, it’s easy to miss or forget certain tasks. Another layer of complexity comes from the need to complete challenges within levels and during free play. Many of these challenges are obscure, requiring experimentation or multiple replays. Additionally, some minigames, such as races, aresurprisingly tricky and can take multiple attempts to win. The user interface, while improved from past LEGO games, doesn’t always make tracking progress intuitive.
Players may find themselves digging through menus to find what’s left to complete. And with so many different gameplay elements such asspace battles, lightsaber duels, stealth missions, and more,mastery of all mechanics is necessary. All of this makesThe Skywalker Sagaa fun but daunting task to 100%, requiring 80 to 100 hours of gameplay and quite a bit of grinding.
4LEGO 2K Drive Takes A While To 100%
A Not-Very-Fun & Time-Consuming Grind
LEGO 2K Driveoffers a colorful, creative take on anopen-world LEGO racing game, but fully completing it proves to be a frustrating grind. While itsvisuals and vehicle customizationare appealing,the path to 100% completion is packed with repetitive objectives, unbalanced difficulty spikes, and tedious side content that lacks variety. The game includes hundreds of collectibles, mini-games, races, and challenges scattered across several regions. Many of these tasks feel copy-pasted, with minimal variation in gameplay or strategy.
Victories inLEGO 2K Driveunlock flags, which are used to gain entrance to Grand Brick Arenas around Bricklandia, eventually granting access is to the Sky Cup Grand Prix.
Progress depends on collecting many flags, gears, and other scattered items, which can be time-consuming and sometimes poorly marked on the map. The lack of a comprehensive in-game tracker further complicates the hunt. Skill-based challenges, such as precision driving or time trials,ramp up in difficulty without much warning. These sections can feel punishing, especially given the loose vehicle controls and “floaty” physics that don’t always respond predictably. Some events require near-perfect runs, with small mistakes leading to restarts.
As for its reception,LEGO 2K Drivehasn’t been highly praised due to its inclusion of microtransactions,especially in a title aimed at younger audiences. The inclusion of real-money purchases for cosmetics and even gameplay advantages undermines the experience (this is true for pretty much all games with microtransactions). Critics and players have also pointed out the bland writing and uninspired story, which lacks the charm expected from aLEGOtitle. While there’s enjoyment to be found, the grind-heavy structure and gross monetization turns most players off from completing this game to 100%.
3LEGO City Undercover Has Over 450 Collectibles
100% Requires Luck & Dedication
LEGO City Undercoveris one of the most expansive and content-richLEGOgames, butreaching 100% completion is a major undertakingthat requires extensive time, exploration, and patience. Set in a massive open-world city with distinct districts, the game is packed with over 450 collectibles, including Super Bricks, Character Tokens, Vehicle Tokens, Red Bricks, and disguise-specific challenges. One of the main reasons it’s difficult to fully complete is the sheer volume and density of the content, and the randomization of necessary loot crates is rough if you’re unlucky with RNG.
It can take approximately 90 to 100 hours to 100%LEGO City Undercover, though some players have been able to do it in as little as 50 hours, which is still a massive time commitment.
The map is cluttered with collectibles,many of which are hidden in obscure or hard-to-reach places. Some items are locked behind puzzles that require using specific disguises and abilities unlocked later in the game, meaning players often have to revisit every area multiple times. Many activities are not clearly marked, and the in-game map lacks precision. Some collectibles don’t appear until you’ve completed particular story missions, meaning it’s easy to miss them if you’re not carefully tracking progress.
Additionally, the game includes100 vehicle stunts, 17 districts to fully explore, and dozens of bonus missionsthat don’t clearly contribute to the completion percentage but must still be done. Another layer of complexity comes from the fact that some achievements or tasks don’t register correctly unless completed in a certain order or with specific conditions, leading to confusion or replays. There are also 40 unlockable vehicles and 290 character costumes, requiring extensive in-game currency and discovery. CompletingLEGO City Undercoverisn’t just about playing thoroughly - it requires luck and a serious time commitment.
2LEGO Worlds Is A Massive Undertaking To 100%
A Challenging LEGO Sandbox Experience
LEGO Worldstakes a sandbox approach to theLEGOformula, offering an open experience centered on exploration, building, and discovery. While this freedom is a core appeal, it also makes 100% completion especially difficult, requiring persistence, attention to detail, and a lot of time spent on unpredictable tasks. To fully complete the game, players must collect over 100 gold bricks, unlock every biome, discover andscan hundreds of objects, creatures, and characters with the Discovery Tool,and acquire all vehicles and props.
Unlike traditionalLEGOgames, which guide players through levels,LEGO Worldsoffers very little structure, meaning you have to create your own path, and it’s easy to get lost in the chaos.One major challenge lies in the randomness of world generation.Key discoveries are tied to procedurally generated worlds, so finding certain rare items or characters can become a lengthy process of world-hopping and waiting for the right conditions. Some quest-givers or required objects only appear under specific circumstances, with no guaranteed spawn rate, making progress feel inconsistent overall.
Ultimately, completing LEGO Worlds is more about persistence than skill.
Additionally, the game’s interface and tracking tools are not always intuitive. It’s hard to know exactly what you’re missing, and managing discovered items across different worlds can be overwhelming. Some quests require building specific structures, butimprecise controls and awkward camera angles make these tasks more frustrating than fun. Ultimately, completingLEGO Worldsis more about persistence than skill. It’s a vast digital LEGO box, but finishing it to 100% means combing through endless possibilities, taking extreme patience and commitment.
1LEGO Dimensions Is The Hardest Game To 100%
Toys-To-Life Means You Need Deep Pockets To Complete This One
LEGO Dimensionsstands out from otherLEGOgames due to its toys-to-life integration, requiring players to buy real-world physical LEGO figures and vehicles. While the concept is inventive and the crossover between franchises is exciting,100% completion is an incredibly complex and costly challenge, both in terms of time and money. The game spans dozens of IPs (intellectual properties), fromThe Wizard of OztoPortaltoScooby-Doo, each with its own unique mechanics, voice actors, and environments.
To unlock all areas and collectibles, players must own specific physical mini-figures and vehicles, many of which are sold separately in Fun, Team, and Level Packs. Some in-game puzzles or areas are only accessible with particular character abilities, meaning full completion is impossible without purchasing a large portion of the available figures.This creates a significant barrier for those unwilling or unable to invest hundreds of dollars. Even with all the figures, tracking and completing every level, adventure world, race, and hidden collectible requires exhaustive backtracking.
Without careful planning and considerable dedication, reaching 100% can feel nearly impossible.
The game includes over 1,000 Gold Bricks, and many challenges are tied to specific character interactions or vehicles, making the process especially intricate. Managing the physical portal adds another layer of difficulty, asplayers must physically rearrange toys in real-time during gameplay.Technical issues like long load times, portal glitches, and recognition errors further complicate the journey. Without careful planning and considerable dedication, reaching 100% can feel nearly impossible.
The path to 100% for all the above LEGO entries takes considerable time investment, and they are all packed with obscure challenges, often hindered by clunky interfaces or ridiculous requirements. For completionists, theseLEGOtitles demand not just skill, but strategy, patience, and sometimes, deep pockets.
