head to head
Batman: Arkham City asks more than LEGO Star Wars II: The Original Trilogy, and the gap is execution.

Execution · Practiced Mastery
An open-city sequel deepening freeflow combat and predator gadget play.

Optimization · Practiced Mastery
A forgiving family collect-athon testing completionist puzzle-solving.
Batman: Arkham City leans Execution (Practiced Mastery); LEGO Star Wars II: The Original Trilogy leans Optimization (Practiced Mastery).
Batman: Arkham City leans clearly harder on execution.
Batman: Arkham City
Combo chains and counters need timing.
LEGO Star Wars II: The Original Trilogy
Forgiving combat and platforming for all ages
Batman: Arkham City leans a little harder on reads, though the gap is small.
Batman: Arkham City
Enemies scripted, not adaptive.
LEGO Star Wars II: The Original Trilogy
Enemies are trivial fixed scripts
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Batman: Arkham City
Fixed encounters and challenges.
LEGO Star Wars II: The Original Trilogy
Authored levels hold no real randomness
Batman: Arkham City leans a little harder on optimization, though the gap is small.
Batman: Arkham City
Gadget combos and challenge maps learnable.
LEGO Star Wars II: The Original Trilogy
Minikit hunting and ability-gated puzzles are the depth
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.
