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
Card-battle strategy testing deckbuilding math against draw luck.

Optimization · Pure Optimization
Team-building and type-matchup optimization, with RNG layers and optional human prediction online.
Etherlords II leans Optimization (Pure Optimization); Pokémon White Version 2 leans Optimization (Pure Optimization).
Pokémon White Version 2 leans a little harder on execution, though the gap is small.
Etherlords II
Turn-based card play, no dexterity
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.
Etherlords II
Mostly AI duels; rare human matches add light bluffing
Pokémon White Version 2
Optional human PvP adds prediction; campaign AI is scripted
Etherlords II leans a little harder on variance, though the gap is small.
Etherlords II
Card draws decide what each duel offers
Pokémon White Version 2
Encounter rolls, catches and damage ranges shape runs
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Etherlords II
Deck construction and mana sequencing are deeply solvable
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.
