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

Execution · Practiced Mastery
A kart racer demanding precise boost-chain execution and route optimisation over item luck.

Execution · Practiced Mastery
Tests fast maze execution and ghost-train routing under randomized attack pressure.
Crash Team Racing Nitro-Fueled leans Execution (Practiced Mastery); Pac-Man 99 leans Execution (Practiced Mastery).
Crash Team Racing Nitro-Fueled leans a little harder on execution, though the gap is small.
Crash Team Racing Nitro-Fueled
Boost-chain execution and power-slide timing are the lead skill
Pac-Man 99
Maze steering at speed under jammer pressure decides survival
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Crash Team Racing Nitro-Fueled
Human multiplayer has light item-use anticipation
Pac-Man 99
98 opponents are anonymous noise, not readable minds
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Crash Team Racing Nitro-Fueled
Item boxes and battle pickups introduce real outcome randomness
Pac-Man 99
Incoming attacks and ghost spawns randomize each match
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Crash Team Racing Nitro-Fueled
Track-specific boost chains and shortcut routes are fully memorisable
Pac-Man 99
Ghost-train routing and target strategies have known best lines
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.
