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 · Practiced Mastery
An open-world pirate adventure where upgrading the Jackdaw matters more than the blade.

Optimization · Practiced Mastery
Boulder-steering races layered over light tower-defense placement decisions.
Assassin's Creed IV: Black Flag leans Optimization (Practiced Mastery); Rock of Ages 3: Make & Break leans Optimization (Practiced Mastery).
Rock of Ages 3: Make & Break leans a little harder on execution, though the gap is small.
Assassin's Creed IV: Black Flag
Naval broadsides and boarding need modest timing
Rock of Ages 3: Make & Break
Steering the boulder through obstacles takes moderate motor control
Rock of Ages 3: Make & Break leans a little harder on reads, though the gap is small.
Assassin's Creed IV: Black Flag
Multiplayer deception mode; campaign is scripted
Rock of Ages 3: Make & Break
Human opponents vary defenses but options are shallow
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Assassin's Creed IV: Black Flag
Weather, convoys, and hunting spawns
Rock of Ages 3: Make & Break
Unit unlocks and physics add light chaos
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Assassin's Creed IV: Black Flag
Ship upgrades and fleet economy drive progress
Rock of Ages 3: Make & Break
Defense placement and boulder routing reward planning
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.
