head to head
StarCraft II: Wings of Liberty asks more than NBA 2K11, and the gap is execution.

Acclaimed basketball sim where playcalling and matchup reads decide online games.

Execution · Grand Arena
Real-time strategy where hands, reads, and build optimization all matter at the top.
NBA 2K11 leans Execution (Grand Arena); StarCraft II: Wings of Liberty leans Execution (Grand Arena).
StarCraft II: Wings of Liberty leans clearly harder on execution.
NBA 2K11
Shot-stick timing and dribble moves
StarCraft II: Wings of Liberty
APM, macro, micro-control under pressure
StarCraft II: Wings of Liberty leans clearly harder on reads.
NBA 2K11
Human defenders bait and adapt possession to possession
StarCraft II: Wings of Liberty
1v1 ladder vs adaptive humans modeling you
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
NBA 2K11
Shooting rolls add mild noise
StarCraft II: Wings of Liberty
map spawns minor; mostly known
StarCraft II: Wings of Liberty leans clearly harder on optimization.
NBA 2K11
Playbooks, matchup exploits, and roster knowledge
StarCraft II: Wings of Liberty
build orders, economy curves heavily solved
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.
