head to head
Fallout Shelter asks more than The Council, and the gap is optimization.

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

Optimization · Systems & Chaos
A social-intrigue RPG where you spend skill resources to exploit dinner guests' scripted psychological weaknesses.
Fallout Shelter leans Optimization (Pure Optimization); The Council leans Optimization (Systems & Chaos).
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
The Council
Menu-driven confrontations; no dexterity.
The Council leans a little harder on reads, though the gap is small.
Fallout Shelter
No opponent
The Council
NPCs have vulnerabilities and immunities, but fully scripted.
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
The Council
Hidden character traits and unknown consequences until learned.
Fallout Shelter leans clearly harder on optimization.
Fallout Shelter
Dweller stats and room layout are fully solvable
The Council
Skill points, effort resources and exploiting known weaknesses are systemic.
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.
