head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.

Execution · Grand Arena
A 2D platforming MOBA blending skillshots with live human mind games.

Execution · Competitive PvP
Shot timing and play-calling against opponents who scheme around your habits.
Awesomenauts leans Execution (Grand Arena); NBA 2K16 leans Execution (Competitive PvP).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Awesomenauts
Platforming aim and skillshots reward dexterity.
NBA 2K16
Shot-stick timing and dribble moves gate every possession
Awesomenauts leans a little harder on reads, though the gap is small.
Awesomenauts
Human opponents adapt lanes and picks constantly.
NBA 2K16
Online opponents adjust defensive schemes against your tendencies
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Awesomenauts
Small map and shop randomness.
NBA 2K16
Shot RNG and card packs add bounded randomness
Awesomenauts leans a little harder on optimization, though the gap is small.
Awesomenauts
Builds, timings, and push economy solvable.
NBA 2K16
Playbooks, rotations and roster building reward deep study
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.
