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

Optimization · Pure Optimization
Physics sandbox about engineering medieval siege machines that usually explode beautifully.

Optimization · Pure Optimization
Sitcom puzzle game about rigging perfect prank chains around a fixed routine.
Besiege leans Optimization (Pure Optimization); Neighbours from Hell 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.
Besiege
Piloting wobbly contraptions takes some hand skill
Neighbours from Hell
Timing pranks between patrol windows
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Besiege
Static castles and scripted defenders
Neighbours from Hell
The neighbour loops a fixed routine
Neighbours from Hell leans a little harder on variance, though the gap is small.
Besiege
Deterministic physics and fixed objectives
Neighbours from Hell
Routine unknown on first attempt, then converges
Besiege leans a little harder on optimization, though the gap is small.
Besiege
Machine engineering is the whole game
Neighbours from Hell
Sequencing pranks for maximum combo rating
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.
