This paper surveys the use of foundation models in game AI across roles like playing, modeling, design, and evaluation, highlighting transferability challenges and the need for game-specific validation.
StatePlay proposes a state-aware game world model that jointly predicts visual content and game states to generate mechanics-consistent game rollouts, achieving 18.6% improvement in mechanics fidelity.
ReactiveGWM is a reactive game world model that enables dynamic player-NPC interactions by decoupling player controls from NPC behaviors using diffusion models and cross-attention modules, achieving zero-shot strategy transfer across different games.
