Deep Analysis
Background
In recent years, significant progress has been made in video generation and world models. Many approaches attempt to learn environment dynamics from large-scale video datasets by training generative models. However, existing datasets often provide only simple action annotations with limited semantic meaning, making it difficult for models to learn structured action-conditioned dynamics and maintain consistent evolution over long horizons. The introduction of the WildWorld dataset aims to address these issues by providing explicit state annotations and a rich action space, offering a new platform for dynamic world modeling in generative ARPGs.
Core Problem
Existing datasets often lack diverse and semantically meaningful action spaces, making it difficult for models to learn structured world dynamics and maintain consistent evolution over long horizons. Additionally, actions are directly tied to visual observations, making it challenging for models to disentangle state transitions from observation variations. These issues limit the performance of current models in long-horizon prediction tasks, where small errors accumulate over time, leading to noticeable inconsistencies or instability in the generated results.
Innovation
The WildWorld dataset addresses these challenges by automatically collecting data from a AAA action role-playing game, offering over 108 million frames and more than 450 actions, covering various interaction scenarios such as movement, attacks, and skill casting. The dataset is designed to address the problem of actions being directly tied to visual observations in existing datasets. By providing explicit state annotations, WildWorld enables models to better learn action-conditioned state transitions, thereby supporting long-horizon world state consistency modeling.

Plain Language Accessible to non-experts
Imagine you're playing a complex role-playing game. There are many characters, each with different actions like attacking, moving, and casting spells. Now, suppose you want a computer to learn how to control these characters in the game as smartly as you do. That's what the WildWorld dataset does. It's like a huge library of game recordings, capturing every action and state of each character in the game. Through these recordings, computers can learn how to make the right decisions in the game, just like an experienced player.
But WildWorld is not just an ordinary library of recordings. It also provides the 'secret information' behind each action, like the skeleton of the character, the state of the world, and the position of the camera. This information acts like a 'manual' for the game, helping the computer understand the true meaning of each action.
By learning from this information, computers can make smarter decisions in the game, like knowing when to attack and when to dodge. This ability is crucial for developing smarter game characters and more complex game worlds.
In short, the WildWorld dataset is like a 'wisdom book' for games, helping computers learn how to make smart decisions in complex game worlds.

Abstract
Dynamical systems theory and reinforcement learning view world evolution as latent-state dynamics driven by actions, with visual observations providing partial information about the state. Recent video world models attempt to learn this action-conditioned dynamics from data. However, existing datasets rarely match the requirement: they typically lack diverse and semantically meaningful action spaces, and actions are directly tied to visual observations rather than mediated by underlying states. As a result, actions are often entangled with pixel-level changes, making it difficult for models to learn structured world dynamics and maintain consistent evolution over long horizons. In this paper, we propose WildWorld, a large-scale action-conditioned world modeling dataset with explicit state annotations, automatically collected from a photorealistic AAA action role-playing game (Monster Hunter: Wilds). WildWorld contains over 108 million frames and features more than 450 actions, including movement, attacks, and skill casting, together with synchronized per-frame annotations of character skeletons, world states, camera poses, and depth maps. We further derive WildBench to evaluate models through Action Following and State Alignment. Extensive experiments reveal persistent challenges in modeling semantically rich actions and maintaining long-horizon state consistency, highlighting the need for state-aware video generation.
