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
A Revolutionary War entry mixing frontier stealth, naval battles, and homestead building.

Optimization · Practiced Mastery
A BioWare RPG testing build choices and style counters over reflexes.
Assassin's Creed III leans Optimization (Practiced Mastery); Jade Empire: Special Edition 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 III
Frontier traversal and counter combat stay forgiving
Jade Empire: Special Edition
Martial-arts combat is real-time but forgiving
Assassin's Creed III leans a little harder on reads, though the gap is small.
Assassin's Creed III
Multiplayer mode involved human deception
Jade Empire: Special Edition
Enemies cycle fixed styles without modelling you
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Assassin's Creed III
Fixed story missions
Jade Empire: Special Edition
Story branches are choices, not hidden randomness
Jade Empire: Special Edition leans a little harder on optimization, though the gap is small.
Assassin's Creed III
Homestead economy and naval upgrades
Jade Empire: Special Edition
Style counters, stat builds and dialogue paths are solvable
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.
