Building comparison
head to head
Half-Life: SourcevsJak 3
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.
Half-Life: Source
Execution · Practiced Mastery
Aim and movement through a fully scripted campaign that route knowledge solves.
Jak 3
Execution · Practiced Mastery
Trilogy closer adding desert vehicles and dark-light eco powers to the formula.
Half-Life: Source leans Execution (Practiced Mastery); Jak 3 leans Execution (Practiced Mastery).
Half-Life: SourceJak 3
Axis by axis
Execution6 vs 6
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Half-Life: Source
Aim, movement and platforming through Black Mesa's gauntlets
Jak 3
Platforming, shooting, and vehicle handling
Reads0 vs 0
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Half-Life: Source
Marines and aliens run impressive but fixed scripts
Jak 3
Enemies run fixed scripts
Variance1 vs 1
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Half-Life: Source
Fully authored campaign, nothing random
Jak 3
Deterministic desert and city
Optimization5 vs 5
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Half-Life: Source
Route knowledge and resource management trivialise replays
Jak 3
Upgrade paths and mission approach choices
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.
