Building comparison
head to head
Half-Life 2vsTron Run/r
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.
Half-Life 2
Execution · Pure Mechanics
Landmark FPS built on physics puzzles and tight gunplay.
Tron Run/r
Execution · Pure Mechanics
Twitch reactions and memorised lines through fast scripted obstacle courses.
Half-Life 2 leans Execution (Pure Mechanics); Tron Run/r leans Execution (Pure Mechanics).
Half-Life 2Tron Run/r
Axis by axis
Execution6 vs 7
Tron Run/r leans a little harder on execution, though the gap is small.
Half-Life 2
Gravity gun and shooting demand precision.
Tron Run/r
High-speed running, jumping and disc throws under relentless pacing
Reads1 vs 0
Half-Life 2 leans a little harder on reads, though the gap is small.
Half-Life 2
Combine AI scripted, non-adaptive.
Tron Run/r
Obstacle streams are scripted, not an adapting mind
Variance1 vs 2
Tron Run/r leans a little harder on variance, though the gap is small.
Half-Life 2
Almost no randomness.
Tron Run/r
Stream mode shuffles segments but each piece is learnable
Optimization3 vs 4
Tron Run/r leans a little harder on optimization, though the gap is small.
Half-Life 2
Linear progression with no builds.

Score chains reward memorising layouts and optimal lines
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.
