Half-Life 2vsRunbow
Runbow asks more than Half-Life 2, and the gap is variance.
Half-Life 2
Execution · Pure Mechanics
Landmark FPS built on physics puzzles and tight gunplay.
Runbow
Execution · Pure Mechanics
Reaction-speed platform racing where shifting colours keep redrawing the level under you.
Half-Life 2 leans Execution (Pure Mechanics); Runbow leans Execution (Pure Mechanics).
Half-Life 2Runbow
Axis by axis
Execution6 vs 7
Runbow leans a little harder on execution, though the gap is small.
Half-Life 2
Gravity gun and shooting demand precision.
Runbow
Fast platform racing through vanishing platforms is pure reaction
Reads1 vs 3
Runbow leans clearly harder on reads.
Half-Life 2
Combine AI scripted, non-adaptive.
Runbow
Light jostling with human racers, but little deep prediction
Variance1 vs 4
Runbow leans clearly harder on variance.
Half-Life 2
Almost no randomness.
Runbow
Colour swaps and party chaos randomise each race
Optimization3 vs 2
Half-Life 2 leans a little harder on optimization, though the gap is small.
Half-Life 2
Linear progression with no builds.
Runbow
Minimal systems - momentum tricks and level memory only
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.
