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

Optimization · Practiced Mastery
Genre-bending action-RTS where you play the wizard on the field, trading souls and god favors.

Optimization · Practiced Mastery
Tolkien-licensed RTS with freeform base building and large-scale faction warfare.
Sacrifice leans Optimization (Practiced Mastery); The Lord of the Rings: The Battle for Middle-earth II leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Sacrifice
Third-person spellcasting and creature micro in real time
The Lord of the Rings: The Battle for Middle-earth II
Moderate APM demands, forgiving unit control
The Lord of the Rings: The Battle for Middle-earth II leans a little harder on reads, though the gap is small.
Sacrifice
Soul-stealing duels reward predicting the enemy wizard
The Lord of the Rings: The Battle for Middle-earth II
Human opponents in skirmish reward prediction
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Sacrifice
Mostly deterministic combat
The Lord of the Rings: The Battle for Middle-earth II
Mostly open information, light randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Sacrifice
God spell picks, soul economy, and army composition matter
The Lord of the Rings: The Battle for Middle-earth II
Economy, base layout, and faction counters drive wins
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.
