head to head
Red Dead Redemption 2 asks more than Harry Potter and the Prisoner of Azkaban, and the gap is execution.

Optimization · Practiced Mastery
A gentle licensed adventure testing basic puzzle matching and collectible hunting.

Execution · Practiced Mastery
A cinematic open-world western leaning on shooting feel and atmosphere.
Harry Potter and the Prisoner of Azkaban leans Optimization (Practiced Mastery); Red Dead Redemption 2 leans Execution (Practiced Mastery).
Red Dead Redemption 2 leans clearly harder on execution.
Harry Potter and the Prisoner of Azkaban
Simple spell-casting and platforming aimed at younger players
Red Dead Redemption 2
Gunplay and Dead Eye reward aim and timing.
Red Dead Redemption 2 leans a little harder on reads, though the gap is small.
Harry Potter and the Prisoner of Azkaban
All enemies and puzzles are fully scripted
Red Dead Redemption 2
Enemies use scripted AI patterns, not adaptation.
Red Dead Redemption 2 leans a little harder on variance, though the gap is small.
Harry Potter and the Prisoner of Azkaban
Hidden collectible locations are fixed once discovered
Red Dead Redemption 2
Some hunting and weather randomness, lightly hidden.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Harry Potter and the Prisoner of Azkaban
Matching the right character's spell to each puzzle
Red Dead Redemption 2
Loadouts and routes solvable but loose.
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.
