head to head
StarCraft asks more than Gigantic: Rampage Edition, and the gap is optimization.

Execution · Grand Arena
A team-based hero shooter testing aim, prediction of opponents, and objective coordination.

Optimization · Grand Arena
A real-time strategy classic where perfected build orders and mechanical speed decide most matches.
Gigantic: Rampage Edition leans Execution (Grand Arena); StarCraft leans Optimization (Grand Arena).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Gigantic: Rampage Edition
Aiming abilities and dodging in real-time hero combat matters
StarCraft
APM and micro control ceiling is huge
Gigantic: Rampage Edition leans a little harder on reads, though the gap is small.
Gigantic: Rampage Edition
Predicting human teammates and enemies drives 5v5 outplays
StarCraft
scouting and predicting human opponent builds
Gigantic: Rampage Edition leans a little harder on variance, though the gap is small.
Gigantic: Rampage Edition
Little randomness; outcomes hinge on team play
StarCraft
minimal hidden info beyond fog of war
StarCraft leans clearly harder on optimization.
Gigantic: Rampage Edition
Ability upgrades, objective control and team comp planning
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.
