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

Execution · Competitive PvP
Stick-skill basketball execution layered with predicting a human opponent's play-calling.

Execution · Pure Mechanics
Classic WWII shooter whose objective-based multiplayer defined a genre.
NBA 2K10 leans Execution (Competitive PvP); Return to Castle Wolfenstein leans Execution (Pure Mechanics).
Return to Castle Wolfenstein leans a little harder on execution, though the gap is small.
NBA 2K10
Shot timing, dribble moves and defense need real stick skill
Return to Castle Wolfenstein
Fast strafing and precise hitscan aim dominate duels
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
NBA 2K10
Human opponents' play-calling and tendencies must be predicted
Return to Castle Wolfenstein
Multiplayer objective pushes hinge on outguessing human defense
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
NBA 2K10
Shot RNG and bounces add modest game-to-game noise
Return to Castle Wolfenstein
Fixed objectives and scripted singleplayer enemies, little randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
NBA 2K10
Roster knowledge, play-calling and matchup exploitation reward study
Return to Castle Wolfenstein
Objective timings, class roles, and routes reward planning
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.
