GameCraft-Bench - Core Mechanics: leaderboard
Metric: Core Mechanics score (%): rubric score for core mechanics (the specified gameplay rules and interactions work), on the 140 GameCraft-Bench tasks (15 game families; complete Godot projects built from natural-language game specifications): a project that fails to launch or submits no parsable demonstration trace scores zero; otherwise the verifier replays the agent's mouse and keyboard traces into gameplay video and frames and a GPT-5.5 multimodal judge scores them against hidden rubric items; higher is better.
