head to head
Dota Underlords asks more than Crusader Kings II, and the gap is variance.

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

Optimization · Systems & Chaos
Valve's autobattler where eight players manage economy and units around a shared random shop.
Crusader Kings II leans Optimization (Systems & Chaos); Dota Underlords 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
Dota Underlords
Drag-and-drop placement, no twitch component
Dota Underlords leans a little harder on reads, though the gap is small.
Crusader Kings II
AI characters scripted not adaptive
Dota Underlords
Scouting lobbies and contesting opponents' compositions
Dota Underlords leans clearly harder on variance.
Crusader Kings II
dynastic events, traits, intrigue
Dota Underlords
Random shop rolls and item drops drive every game
Dota Underlords leans a little harder on optimization, though the gap is small.
Crusader Kings II
succession, marriages, claims plannable
Dota Underlords
Economy management and composition math dominate
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.
