head to head
Mario Kart 8 Deluxe asks more than Temple Run 2, and the gap is reads.

Execution · Twitch Chaos
A kart racer where item luck collides with optimized lines and builds.

Execution · Twitch Chaos
Sustained reaction-swiping against procedurally shuffled obstacle segments.
Mario Kart 8 Deluxe leans Execution (Twitch Chaos); Temple Run 2 leans Execution (Twitch Chaos).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Mario Kart 8 Deluxe
Drift boosts, snaking, and item timing demand precision.
Temple Run 2
Split-second swipes at rising speed are the whole game
Mario Kart 8 Deluxe leans clearly harder on reads.
Mario Kart 8 Deluxe
Human racers bait and block items but mostly reactive.
Temple Run 2
No opponent; the track does not adapt
Mario Kart 8 Deluxe leans a little harder on variance, though the gap is small.
Mario Kart 8 Deluxe
Item distribution heavily randomized by position.
Temple Run 2
Procedural track segments keep each run unpredictable
Mario Kart 8 Deluxe leans clearly harder on optimization.
Mario Kart 8 Deluxe
Kart build, line, and shortcut knowledge define top times.
Temple Run 2
Powerup upgrades and objectives add a thin meta layer
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.
