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
A PSP stealth-action side story following Altair's hunt for Templars on Cyprus.

Execution · Practiced Mastery
The template Far Cry: outposts, predators, and a tropical sandbox.
Assassin's Creed: Bloodlines leans Optimization (Practiced Mastery); Far Cry 3 leans Execution (Practiced Mastery).
Far Cry 3 leans a little harder on execution, though the gap is small.
Assassin's Creed: Bloodlines
Simplified PSP combat and climbing demand little precision
Far Cry 3
Shooting and stealth fundamentals matter.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Assassin's Creed: Bloodlines
Templar guards are entirely scripted
Far Cry 3
Pirate AI uses fixed alert patterns.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Assassin's Creed: Bloodlines
Compact fixed maps leave few surprises
Far Cry 3
Wildlife and outpost spawns randomized.
Assassin's Creed: Bloodlines leans a little harder on optimization, though the gap is small.
Assassin's Creed: Bloodlines
Route knowledge and counter timing are quickly solved
Far Cry 3
Skill trees and weapon mods quickly mastered.
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.
