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
Dystopian management adventure about a landlord spying on tenants for a totalitarian state.

Optimization · Systems & Chaos
A lighter loot ARPG of frontier adventurers with class relics and buildable forts.
Beholder leans Optimization (Pure Optimization); Torchlight III leans Optimization (Systems & Chaos).
Torchlight III leans a little harder on execution, though the gap is small.
Beholder
Simple point-and-click landlord actions
Torchlight III
Simple skill rotation and dodging
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Beholder
Tenants follow scripted schedules, not adaptive
Torchlight III
Monsters are scripted fodder
Torchlight III leans a little harder on variance, though the gap is small.
Beholder
Tenant events and directives surprise first runs
Torchlight III
Loot and map randomness standard for genre
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Beholder
Money, time, and blackmail decision routing
Torchlight III
Relic and skill builds, fort crafting bonuses
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.
