Abstract
Problem: How do you design a game world where players can tackle content in any order, with any character build, while maintaining a coherent story?
Approach: Tim Cain draws on his experience from Fallout (1994) through The Outer Worlds, outlining a systematic framework for nonlinear quest design, branching narratives, and player freedom.
Findings: Nonlinear design requires three core systems working together: gating mechanisms that are aspirational rather than punishing, a "football model" of branching storylines with fixed checkpoints, and the discipline to maintain multiple solution paths all the way through to the ending.
Key insight: Every main quest must be solvable through fighting, talking, and stealth — and the game's ending must honor that same principle, or the entire nonlinear design collapses.
