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.

Optimization · Pure Optimization
A zombie survival crafter where horde-night base design carries the game.

Optimization · Practiced Mastery
Building card decks that out-value scripted bosses in real-time battles.
7 Days to Die leans Optimization (Pure Optimization); Kingdom Hearts Re:Chain of Memories leans Optimization (Practiced Mastery).
Kingdom Hearts Re:Chain of Memories leans a little harder on execution, though the gap is small.
7 Days to Die
Aim and movement during horde nights matter.
Kingdom Hearts Re:Chain of Memories
Real-time card play needs timing but not twitch mastery
7 Days to Die leans a little harder on reads, though the gap is small.
7 Days to Die
Zombie AI is largely scripted with minor pathing adaptation.
Kingdom Hearts Re:Chain of Memories
Bosses break cards with scripted, learnable values
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
7 Days to Die
World generation and loot rolls randomized.
Kingdom Hearts Re:Chain of Memories
Card draws within your deck vary each fight
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
7 Days to Die
Base design and horde-night kill funnels dominate.
Kingdom Hearts Re:Chain of Memories
Deck construction and sleight knowledge dominate outcomes
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.
