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

Optimization · Systems & Chaos
Medieval dynasty sim with chaotic event-driven stories.

Optimization · Systems & Chaos
N64 arena battler where rental and imported Pokemon fight in 3D tournaments and mini-games.
Crusader Kings II leans Optimization (Systems & Chaos); Pokemon Stadium 2 leans Optimization (Systems & Chaos).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Crusader Kings II
pausable, no reflex
Pokemon Stadium 2
Menu-driven turn battles; no physical demands
Pokemon Stadium 2 leans a little harder on reads, though the gap is small.
Crusader Kings II
AI characters scripted not adaptive
Pokemon Stadium 2
Human PvP cups reward prediction; AI cups are mappable
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Crusader Kings II
dynastic events, traits, intrigue
Pokemon Stadium 2
Accuracy rolls, crits, rental rosters add randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Crusader Kings II
succession, marriages, claims plannable
Pokemon Stadium 2
Team building, movesets, type matchups are solvable
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.
