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

Optimization · Practiced Mastery
The reboot that turned Assassin's Creed into a loot-driven action RPG.

Optimization · Practiced Mastery
A real-time RPG carried by ascension-grid routing and magic crafting.
Assassin's Creed Origins leans Optimization (Practiced Mastery); Final Fantasy XV 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.
Assassin's Creed Origins
Hitbox-based combat needs timing but lenient.
Final Fantasy XV
Real-time combat, modest input demand
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Assassin's Creed Origins
Guard AI scripted, predictable.
Final Fantasy XV
Scripted enemies
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Assassin's Creed Origins
Loot rarity rolls present.
Final Fantasy XV
Loot and ascension variance
Final Fantasy XV leans a little harder on optimization, though the gap is small.
Assassin's Creed Origins
Gear, abilities, target loadouts solvable.
Final Fantasy XV
Ascension grid, magic crafting, party 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.
