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.

Reads · Mind & Math
A card game emphasizing priority-based reads over raw draw variance.

Optimization · Grand Arena
Territory math and dice management entangled with reading human alliances.
Legends of Runeterra leans Reads (Mind & Math); Risk: Global Domination leans Optimization (Grand Arena).
Legends of Runeterra leans a little harder on execution, though the gap is small.
Legends of Runeterra
Clicks only
Risk: Global Domination
Clicking territories takes no physical skill
Legends of Runeterra leans a little harder on reads, though the gap is small.
Legends of Runeterra
Alternating priority and spell mana create bluff layers
Risk: Global Domination
Human diplomacy, truces and betrayal timing cannot be solved
Risk: Global Domination leans a little harder on variance, though the gap is small.
Legends of Runeterra
Less draw RNG than peers but still present
Risk: Global Domination
Dice rolls swing battles and mission cards hide information
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Legends of Runeterra
Tight deckbuilding and sequencing math
Risk: Global Domination
Continent bonuses, troop math and border control are calculable
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.
