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
A Hitman-style Cold War stealth game about a KGB assassin working sandboxed kill missions.

Optimization · Pure Optimization
A third-person tower defense about funneling orc hordes into gleefully lethal trap corridors.
Alekhine's Gun 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.
Alekhine's Gun
Timing takedowns matters less than planning them
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.
Alekhine's Gun
NPC routines are clockwork, never reactive learning
Orcs Must Die!
Orc waves follow fixed paths
Alekhine's Gun leans a little harder on variance, though the gap is small.
Alekhine's Gun
First visits hide patrol routines and disguise rules
Orcs Must Die!
Minor wave composition randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Alekhine's Gun
Mapping routines and disguises reduces missions to solved puzzles
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.
