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
Real-time stealth tactics where each mission is a clockwork puzzle of guard routes.

Optimization · Pure Optimization
A third-person tower defense about funneling orc hordes into gleefully lethal trap corridors.
Commandos: Behind Enemy Lines 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: Behind Enemy Lines
Timing guard windows takes precise clicks
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: Behind Enemy Lines
Patrols are fixed routes, never adaptive
Orcs Must Die!
Orc waves follow fixed paths
Orcs Must Die! leans a little harder on variance, though the gap is small.
Commandos: Behind Enemy Lines
All guard cones and routes are visible
Orcs Must Die!
Minor wave composition randomness
Commandos: Behind Enemy Lines leans a little harder on optimization, though the gap is small.
Commandos: Behind Enemy Lines
Each mission is a solvable stealth 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.
