head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.

Optimization · Pure Optimization
A vault management sim about optimising dwellers, rooms, and resource loops.

Optimization · Pure Optimization
Supernatural western turn-based tactics where a luck meter replaces pure hit-chance dice.
Fallout Shelter leans Optimization (Pure Optimization); Hard West leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Fallout Shelter
Tapping menus only
Hard West
Turn-based; no physical demands
Hard West leans a little harder on reads, though the gap is small.
Fallout Shelter
No opponent
Hard West
AI follows fixed tactical scripts
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Fallout Shelter
Incident spawns and lunchbox loot rolls
Hard West
Luck meter tames RNG but cards and shots vary
Hard West leans a little harder on optimization, though the gap is small.
Fallout Shelter
Dweller stats and room layout are fully solvable
Hard West
Positioning, ability combos, and luck-system math dominate
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
