head to head
TrackMania 2: Stadium asks more than Half-Life 2, and the gap is execution.

Execution · Pure Mechanics
Landmark FPS built on physics puzzles and tight gunplay.

Execution · Pure Mechanics
Grinding deterministic tracks for the perfect line and the flawless run.
Half-Life 2 leans Execution (Pure Mechanics); TrackMania 2: Stadium leans Execution (Pure Mechanics).
TrackMania 2: Stadium leans clearly harder on execution.
Half-Life 2
Gravity gun and shooting demand precision.
TrackMania 2: Stadium
Perfect inputs ARE the game - hundredths decide leaderboards
Half-Life 2 leans a little harder on reads, though the gap is small.
Half-Life 2
Combine AI scripted, non-adaptive.
TrackMania 2: Stadium
Ghost racing - opponents never interact with your run
Half-Life 2 leans a little harder on variance, though the gap is small.
Half-Life 2
Almost no randomness.
TrackMania 2: Stadium
Fully deterministic physics, identical track every attempt
TrackMania 2: Stadium leans clearly harder on optimization.
Half-Life 2
Linear progression with no builds.
TrackMania 2: Stadium
Finding the optimal racing line is half the hunt
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.
