Axis by axis
Execution1 vs 0
Loop Hero leans harder on execution: Autobattler, almost no inputs.
Reads0 vs 1
Slay the Spire leans harder on reads: Enemy intents shown; behaviour scripted, not adaptive.
Variance5 vs 7
Slay the Spire leans harder on variance: Card and relic offers drive every run.
Optimization9 vs 9
Even - both lean on optimization about the same.
Two games can score the same on an axis and still test it in very different ways - read each rationale, not just the number.
