head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Practiced Mastery
A forgiving brawler-platformer where hijacking the right monster is the only decision.

Execution · Practiced Mastery
Charming physics toy about a wobbly robot climbing a giant plant into the sky.
Crash of the Titans leans Execution (Practiced Mastery); Grow Home leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Crash of the Titans
Combo brawling and titan-jacking need light timing
Grow Home
Procedural hand-over-hand climbing coordination
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Crash of the Titans
Titans are scripted mounts, not minds
Grow Home
No opposition of any kind
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Crash of the Titans
Levels are linear and fixed
Grow Home
World fixed; little hidden
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Crash of the Titans
Choosing which titan to ride is shallow strategy
Grow Home
Vine routing toward floating islands
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.
