pausable, no reflex
The Witcher: Adventure Game
Digital board game - clicks only
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.

The Witcher: Adventure Game leans clearly harder on variance.
Crusader Kings II
dynastic events, traits, intrigue
The Witcher: Adventure Game
Dice combat and event card draws dominate single quests
Crusader Kings II leans a little harder on optimization, though the gap is small.

succession, marriages, claims plannable
The Witcher: Adventure Game
Quest routing and risk-odds management reward planning
