Killer Instinct (2013)
Combo Breaker prediction is a pure read-off against an adaptive opponent
StarCraft
scouting and predicting human opponent builds
Variance1 vs 1

No RNG; all mechanics are fully visible
StarCraft
minimal hidden info beyond fog of war
Optimization7 vs 9
StarCraft leans clearly harder on optimization.

Instinct activation timing and optimal opener routes are well-studied
StarCraft
build orders and economy are near-solvable
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.
