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

Optimization · Pure Optimization
A systemic immersive sim where augmentation choices and route planning determine how every obstacle falls.

Optimization · Pure Optimization
Steampunk colony defense against scripted zombie waves.
Deus Ex leans Optimization (Pure Optimization); They Are Billions leans Optimization (Pure Optimization).
Deus Ex leans a little harder on execution, though the gap is small.
Deus Ex
Aiming and movement matter but never define victory
They Are Billions
some pause-based defense placement
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Deus Ex
NPCs follow scripted patrol routes, not adaptive modelling
They Are Billions
zombie AI not adaptive
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Deus Ex
Enemy placements and item locations are fixed but initially hidden
They Are Billions
map gen, swarm timing
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Deus Ex
Augmentation builds, routes, and tool choices are the core system
They Are Billions
economy and wall placement solvable
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.
