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 · Pure Optimization
A Napoleonic strategy game testing empire economy and battlefield formation play.

Optimization · Pure Optimization
A charming JRPG carried by familiar evolution and party-build routing.
Imperial Glory leans Optimization (Pure Optimization); Ni no Kuni: Wrath of the White Witch 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.
Imperial Glory
Pausable battles and turn-based empire management, minimal dexterity
Ni no Kuni: Wrath of the White Witch
Hybrid action-turn combat, low input demand
Imperial Glory leans a little harder on reads, though the gap is small.
Imperial Glory
Human multiplayer battles allow some feinting, AI doesn't adapt
Ni no Kuni: Wrath of the White Witch
Scripted enemies
Ni no Kuni: Wrath of the White Witch leans a little harder on variance, though the gap is small.
Imperial Glory
Diplomacy outcomes add modest uncertainty
Ni no Kuni: Wrath of the White Witch
Familiar catch and drop rolls
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Imperial Glory
Economy, research and Napoleonic battle formations are the solvable core
Ni no Kuni: Wrath of the White Witch
Familiar evolution and party routing rewarded
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.
