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
The arcade rally classic where reading surfaces and holding perfect drifts decides everything.

Execution · Pure Mechanics
Arcade run-and-gun reflexes against fully memorisable boss patterns.
Sega Rally Championship leans Execution (Pure Mechanics); Sunset Riders 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.
Sega Rally Championship
Surface-aware drift control is the entire skill ceiling.
Sunset Riders
Dodging bullet spreads and snap-shooting bosses is everything
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Sega Rally Championship
Time-attack against scripted AI; no adaptation.
Sunset Riders
Bandits and bosses cycle memorisable arcade patterns
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Sega Rally Championship
Fixed tracks; nothing hidden after first lap.
Sunset Riders
Spawns are deterministic each credit
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Sega Rally Championship
Learning racing lines per surface converges quickly.
Sunset Riders
Pattern memorisation for one-credit clears is the meta-game
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.
