head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is optimization, and it is a single point.

Optimization · Pure Optimization
A turn-based strategy game built on hero development and army optimization.

Optimization · Pure Optimization
Team-building and type-matchup optimization, with RNG layers and optional human prediction online.
Heroes of Might & Magic: Olden Era leans Optimization (Pure Optimization); Pokémon White Version 2 leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Heroes of Might & Magic: Olden Era
no reflex demand, turn-based strategy
Pokémon White Version 2
Turn-based menus remove any physical ceiling
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Heroes of Might & Magic: Olden Era
human multiplayer opponents adapt strategy
Pokémon White Version 2
Optional human PvP adds prediction; campaign AI is scripted
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Heroes of Might & Magic: Olden Era
combat rolls and map randomness
Pokémon White Version 2
Encounter rolls, catches and damage ranges shape runs
Heroes of Might & Magic: Olden Era leans a little harder on optimization, though the gap is small.
Heroes of Might & Magic: Olden Era
hero builds, economy, army composition
Pokémon White Version 2
Type matchups, EV training and team building are solvable math
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.
