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 tower defense testing optimal tower combinations against scripted waves.

Optimization · Pure Optimization
A tactical RPG solved through long-horizon build and class planning.
Element TD 2 leans Optimization (Pure Optimization); Fire Emblem: Three Houses leans Optimization (Pure Optimization).
Element TD 2 leans a little harder on execution, though the gap is small.
Element TD 2
Light micro on tower placement timing, minimal twitch
Fire Emblem: Three Houses
Menu-driven, no mechanical bar
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Element TD 2
Scripted enemy waves, no adaptive opponent
Fire Emblem: Three Houses
AI follows fixed aggression rules
Fire Emblem: Three Houses leans a little harder on variance, though the gap is small.
Element TD 2
Wave composition known, little hidden information
Fire Emblem: Three Houses
Hit rates and crit RNG affect runs
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Element TD 2
Optimal tower combos and placement IS the game
Fire Emblem: Three Houses
Class routing and build planning dominates
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.
