head to head
Neither is simply harder - they are hard in different places. Fallout: New Vegas demands more execution; Timberborn demands more variance.

Optimization · Pure Optimization
A faction-driven RPG-shooter where build and route planning shape every ending.

Optimization · Pure Optimization
Engineering a beaver colony's water and food systems to survive scheduled drought cycles at growing scale.
Fallout: New Vegas leans Optimization (Pure Optimization); Timberborn leans Optimization (Pure Optimization).
Fallout: New Vegas leans clearly harder on execution.
Fallout: New Vegas
Shooter inputs with VATS assist
Timberborn
Construction and management require no physical precision
Fallout: New Vegas leans a little harder on reads, though the gap is small.
Fallout: New Vegas
Scripted factions and enemies
Timberborn
No adversary exists; droughts are scheduled, not adaptive
Timberborn leans clearly harder on variance.
Fallout: New Vegas
Some loot and crit RNG
Timberborn
Map seed and drought timing carry moderate session-level randomness
Timberborn leans a little harder on optimization, though the gap is small.
Fallout: New Vegas
Faction routing, perks, builds heavily rewarded
Timberborn
Water management, district planning, and beaver worker routing are the engineered core
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.
