head to head
StarCraft asks more than NBA 2K11, and the gap is optimization.

Execution · Grand Arena
Acclaimed basketball sim where playcalling and matchup reads decide online games.

Optimization · Grand Arena
A real-time strategy classic where perfected build orders and mechanical speed decide most matches.
NBA 2K11 leans Execution (Grand Arena); StarCraft leans Optimization (Grand Arena).
StarCraft leans a little harder on execution, though the gap is small.
NBA 2K11
Shot-stick timing and dribble moves
StarCraft
APM and micro control ceiling is huge
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
NBA 2K11
Human defenders bait and adapt possession to possession
StarCraft
scouting and predicting human opponent builds
NBA 2K11 leans a little harder on variance, though the gap is small.
NBA 2K11
Shooting rolls add mild noise
StarCraft
minimal hidden info beyond fog of war
StarCraft leans clearly harder on optimization.
NBA 2K11
Playbooks, matchup exploits, and roster knowledge
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.
