Choose a trainee, two legacy parents, and a six-card Support deck → run an approximately three-year Career by choosing training, rest, outings, races, and skills → build stats, skills, mood, relationships, and meet race goals → finish the scenario and create a trained Uma with inheritance factors → enter Team Trials, seasonal competition, collection, and inheritance → reinvest rewards and assets into the next Career.

Decision and Planning Calculability Breakdown
The affected flow runs through Support depth → Career result contribution; its limiting point is the training growth planning handoff.
Multiple goals, resources, states, rules, and paths cannot be compared on one decision surface, forcing repeated reprioritization.
