head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Pure Mechanics
Pure car control over loose surfaces, sharpened by memorising every stage.

Execution · Pure Mechanics
A frantic SNES space-western gallery shooter about dodging while you shoot.
Colin McRae Rally 2.0 leans Execution (Pure Mechanics); Wild Guns leans Execution (Pure Mechanics).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Colin McRae Rally 2.0
Surface-specific car control at speed decides every stage
Wild Guns
Simultaneous aiming and dodging defines the whole game
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Colin McRae Rally 2.0
Time-trial format - no adaptive opponent on the stage
Wild Guns
Enemy waves are fully scripted
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Colin McRae Rally 2.0
Mid-stage surprises minimal once pace notes are internalised
Wild Guns
Bullet spawns vary slightly until patterns are absorbed
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Colin McRae Rally 2.0
Memorising stages and tuning setups converges times steadily
Wild Guns
Stage routing and pattern memorization converge for high scores
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.
