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
A turn-based 3D space tactics game about flanking fleets across randomized adventures.

Variance · Grand Arena
A digital card game balancing opponent reads against draw variance.
Flotilla leans Optimization (Systems & Chaos); Hearthstone leans Variance (Grand Arena).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Flotilla
Turn-based orders, no twitch demand
Hearthstone
Clicks only, no mechanical skill
Hearthstone leans a little harder on reads, though the gap is small.
Flotilla
Versus mode lets you predict human fleet moves
Hearthstone
Human opponents bluff and adapt mid-match
Hearthstone leans a little harder on variance, though the gap is small.
Flotilla
Randomized encounters and loot drive each adventure
Hearthstone
Draw RNG and discover effects swing games
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Flotilla
3D positioning and flanking angles solve battles
Hearthstone
Deckbuilding, mulligans, and mana curves matter
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.
