A detailed Lego planet with a complete South Park quest and a proper building mode. Picking up, rotating, snapping and throwing individual bricks make this much more than an attractive 3D demo.

What impressesThousands of Lego bricks, recognizable characters, plastic materials and a polished interface form a cohesive world. The full quest can be completed: collect three parts, move a crate and activate the Planet-O-Matic. Walking around the globe, jumping, mouse look, camera switching, building mechanics and pausing work. Dialogue connects the objectives with fitting South Park jokes.

Room to improveThe story is linear and conversations offer no choices. Reloading clears quest progress and building changes. On mobile, the build button overlaps some introductory text; touch controls support walking and jumping, but rotating and throwing bricks require keyboard input.

What impressesDetailed buildings, snowy Lego studs and a clear interface form a cohesive world. Walking around the globe, jumping, E-key conversations and the first quest steps work. Picking up, rotating and moving a crate exposes the hidden fuse. Dialogue offers response choices and fitting jokes about Cartman’s subscription business. Touch controls and a globe overview are included.

Room to improveThe quest is short and linear; loose bricks can be moved, but there is no extensive building mode. Reloading clears progress. The mobile interface occupies considerable screen space and lacks rotate and throw buttons. Stan, Kyle and the fuse were tested in the browser; collecting the capacitor and the finale were not fully completed.

What impressesWalking, jumping, mouse look and E-key conversations work, as do picking up, carrying and throwing bricks. Conversations with Stan, Kyle and Cartman advance the mission to a collection quest. Buildings and objects have collisions, while characters and signs give the world a distinctive identity.

Room to improveThe visual presentation remains fairly simple and progress is not saved. On mobile, the title wraps awkwardly and touch controls are missing. The later battery mission and ending are present in the code but were not played through completely during this evaluation.

The mission is playable from start to finish: talk to Stan, deliver three proof bricks, confront Cartman and restart winter. Kyle and Kenny provide individual clues. A globe overview, sound effects and a working restart round out the experience.

Room to improveYou can walk through the school. The world contains few buildings and the story remains a linear fetch quest without choices or further puzzles. Reloading clears mission progress and moved bricks. Play requires keyboard and mouse; touch controls are absent.

Room to improveA and D move in the opposite direction relative to the camera. Buildings can be walked through, and an invisible town boundary prevents exploring the entire globe. The story is a short collection quest without further puzzles. Moved objects reset after reloading, and there is no restart button.

What impressesWalking and jumping on the globe, mouse look, camera zoom, E-key dialogue and carrying, dropping and throwing objects work. The quest can be completed: find three underpants, get Cartman’s password through Mr. Mackey and Chef, retrieve the Profit Core and return it. Buildings and trees block the player; Play Again restarts the story.

Room to improveA and D move opposite to the camera-relative direction. Figures and buildings are fairly crude, the camera starts close to the player, and the story uses fixed conversations and collection tasks. Reloading clears all progress. Quest and control panels overlap on mobile. Play requires keyboard and mouse, as specified by the brief.

Room to improveW initially moves backwards relative to the viewing direction. Talking to Kyle before Stan leaves the story objective stuck on Kyle, even after talking again. Movement continues while paused. The world and animations are fairly simple. Designed for keyboard and mouse; there are no touch controls.

Jumping, looking around, E-key conversations, and picking up, carrying and dropping Lego bricks work. Cartman’s Cheesy Poofs quest can be completed; Kenny breaks into loose bricks with a fitting joke.

Room to improveOn part of the globe, W moves opposite to the viewing direction. Buildings do not block the player. The world is sparsely furnished and the story is only a short collection quest. Returning the package requires dropping it first and approaching Cartman again. On mobile, the quest overlaps the title; play requires keyboard and mouse.

What impressesWASD movement, jumping, mouse look, E-key conversations, and picking up and placing bricks work. The search for the Golden Founders Brick is playable from start to finish, including a talking vending machine’s clue and a confetti ending. Buildings block the player and pausing stops movement. The interface and dry small-town jokes give the game character.

Room to improveThe requested South Park characters, setting and storyline are absent: this is a generic satirical town with original residents. The world mainly consists of simple planes and blocks, and the mission is one short fetch quest. Placed bricks float above the ground. Selecting a color does not recolor the held brick. E-key conversations remain possible while paused, and reloading resets progress.

What impressesHouses, trees, Lego studs, four custom minifigures and a clear quest interface establish a recognizable theme. Play, the opening dialogue and mouse look work; movement and jump keys respond. Cartman’s boasting, Kyle’s mother and Kenny’s return fit South Park. This assesses the public preview released on 6 October 2026.

Room to improveYou walk on a flat plate rather than the requested globe. The ground check hits the player’s own invisible body, sending you into the air without jumping. Bricks are groups whose child meshes are excluded from object selection, so pickup does not work. The delivery target at z=-55 also lies outside the playable area, which stops at z=-43. The simple collection quest and ending could not be completed. The mobile start screen fits the viewport; touch controls are absent, which alone incurs no deduction for this keyboard-and-mouse brief.

This prevents normal testing of quests and object interactions. The score rewards only what the original submission actually demonstrates; the exact model version is unknown.

What impressesThe start screen has a distinct South Park feel, readable control instructions and an absurd premise: five golden bricks hold the town together. The introduction also fits a narrow viewport. Starting activates pointer lock and displays the first objective; releasing the mouse shows a pause overlay.

Room to improveLine 679 reads camera.pos.z, but camera.pos does not exist. Every animation cycle aborts before drawing the 3D world: the renderer remains at zero frames even after a successful start. No characters, objects or playable quests are visible. The score rewards only the displayed introduction and limited overlay controls; unreachable game code is not credited as working functionality.

01 / THE BRIEF

One shared prompt.

Every model gets this exact brief: a 3D Lego world, keyboard and mouse controls, movable objects and a proper South Park storyline.

Create a 3D world as a globe with a South Park theme. I want to be able to walk through the world using WSAD, interact via 'e', and jump using the spacebar. I also want to be able to rotate the mouse and move objects. I want the world to be made of Lego bricks. Also, make it a game where the characters make typical South Park jokes, and the game must really have a South Park storyline.

02 / THE EVALUATION

How impressive is it?

The score evaluates what the model demonstrates with this brief: the 3D world, creativity, story and working game controls. We test in the browser and inspect the mobile view too. The brief requests keyboard and mouse controls, so missing touch controls do not cost points.
