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

Optimization · Pure Optimization
A narrative horror game tested primarily by puzzle knowledge and sanity-resource management.

Optimization · Pure Optimization
A base-layout and attack-planning puzzle against static player defenses.
Amnesia: Rebirth leans Optimization (Pure Optimization); Boom Beach leans Optimization (Pure Optimization).
Amnesia: Rebirth leans a little harder on execution, though the gap is small.
Amnesia: Rebirth
Stealth and evasion; no real twitch demands
Boom Beach
Tapping troop deployments takes no dexterity
Boom Beach leans a little harder on reads, though the gap is small.
Amnesia: Rebirth
Enemies patrol fixed routes; no adaptive opponent
Boom Beach
Attacks hit static bases - defenders aren't present to adapt
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.

Boom Beach
Scouting reveals most info; matchmaking adds some spread
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Amnesia: Rebirth
Resource management, narrative puzzles and safe-path knowledge are solvable
Boom Beach
Base layouts, troop compositions and timing are the solvable core
