head to head
Mario Kart 8 Deluxe asks more than Dungeon Souls, and the gap is reads.

Execution · Twitch Chaos
Kiting hordes through procedural floors while building around random loot.

Execution · Twitch Chaos
A kart racer where item luck collides with optimized lines and builds.
Dungeon Souls leans Execution (Twitch Chaos); Mario Kart 8 Deluxe leans Execution (Twitch Chaos).
Mario Kart 8 Deluxe leans a little harder on execution, though the gap is small.
Dungeon Souls
Dodging dense enemy hordes demands constant kiting
Mario Kart 8 Deluxe
Drift boosts, snaking, and item timing demand precision.
Mario Kart 8 Deluxe leans clearly harder on reads.
Dungeon Souls
Monsters swarm by script, not strategy
Mario Kart 8 Deluxe
Human racers bait and block items but mostly reactive.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Dungeon Souls
Procedural floors and random loot reshape every run
Mario Kart 8 Deluxe
Item distribution heavily randomized by position.
Mario Kart 8 Deluxe leans a little harder on optimization, though the gap is small.
Dungeon Souls
Character builds and unlock knowledge converge with experience
Mario Kart 8 Deluxe
Kart build, line, and shortcut knowledge define top times.
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.
