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
An endless-runner shooter testing steering and aim against zombie crowds.

Execution · Practiced Mastery
The handheld Mario Kart blending SNES-style handling with item-fueled races.
Into the Dead 2 leans Execution (Practiced Mastery); Mario Kart: Super Circuit leans Execution (Practiced Mastery).
Mario Kart: Super Circuit leans a little harder on execution, though the gap is small.
Into the Dead 2
Steering and aiming while auto-running drives survival
Mario Kart: Super Circuit
Snappy GBA handling rewards precise drift control
Mario Kart: Super Circuit leans a little harder on reads, though the gap is small.
Into the Dead 2
Zombies shamble on scripts, no prediction
Mario Kart: Super Circuit
Mostly AI races, light link-cable PvP
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Into the Dead 2
Spawn placement and pickup drops vary each run
Mario Kart: Super Circuit
Item boxes randomise every race
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Into the Dead 2
Weapon loadout and upgrade choices reward planning
Mario Kart: Super Circuit
Time-trial lines and shortcut routes
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.
