head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.

Execution · Pure Mechanics
The bigger, faster sequel doubling down on chaotic crash physics and stunt minigames.

Execution · Pure Mechanics
A frantic endless runner with retro arcade style.
FlatOut 2 leans Execution (Pure Mechanics); Geki Yaba Runner: Anniversary Edition 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.
FlatOut 2
High-speed control amid wrecks and ragdolls
Geki Yaba Runner: Anniversary Edition
fast reflex timing for endless running
FlatOut 2 leans a little harder on reads, though the gap is small.
FlatOut 2
No adaptive opposition worth modeling
Geki Yaba Runner: Anniversary Edition
no opponent, solo endless runner
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
FlatOut 2
Crash physics and track debris vary every race
Geki Yaba Runner: Anniversary Edition
procedural obstacle generation
FlatOut 2 leans a little harder on optimization, though the gap is small.
FlatOut 2
Track knowledge and car tuning settle into routine
Geki Yaba Runner: Anniversary Edition
minor route/upgrade optimization
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.
