Brainstorm game concepts and write lightweight GDDs with Unreal Engine feasibility built in. Use when the user wants to generate or refine game ideas, pitch a mechanic or hook, scope a new UE project or feature, or produce a game design document. Interviews to converge ideas, then gates each mechanic against what is realistic in UE: gameplay framework, GAS, replication, physics, Niagara, animation, input, and the C++/Blueprint/UnLua split, consulting the matching ue-* skill for evidence before estimating effort. Not for writing engine code itself.
