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

Optimization · Pure Optimization
Real-time tactics where every mission is a clockwork stealth puzzle to be solved.

Optimization · Pure Optimization
A third-person tower defense about funneling orc hordes into gleefully lethal trap corridors.
Commandos 3: Destination Berlin leans Optimization (Pure Optimization); Orcs Must Die! 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.
Commandos 3: Destination Berlin
Tight click timing chaining distractions and kills
Orcs Must Die!
Active shooting supplements the traps
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Commandos 3: Destination Berlin
Guards follow fixed patrol scripts, never adapt
Orcs Must Die!
Orc waves follow fixed paths
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Commandos 3: Destination Berlin
Unknown patrols only until scouted, then fully mapped
Orcs Must Die!
Minor wave composition randomness
Commandos 3: Destination Berlin leans a little harder on optimization, though the gap is small.
Commandos 3: Destination Berlin
Each mission reduces to a solvable sequence puzzle
Orcs Must Die!
Trap placement and kill-corridor economics are the game
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.
