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 · Practiced Mastery
Fast 90s shooter movement and aim through maze levels packed with secrets.

Execution · Practiced Mastery
Memorising scripted boxer patterns and executing split-second counters.
Shadow Warrior leans Execution (Practiced Mastery); Super Punch-Out!! leans Execution (Practiced Mastery).
Super Punch-Out!! leans a little harder on execution, though the gap is small.
Shadow Warrior
Build-engine speed, aim and movement carry every firefight
Super Punch-Out!!
Frame-tight dodges and counters decide every bout
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Shadow Warrior
Multiplayer existed but enemies are scripted spawns
Super Punch-Out!!
Opponents are scripted pattern puzzles, not adapting minds
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Shadow Warrior
Secrets are fixed in place across playthroughs
Super Punch-Out!!
Patterns are fixed once learned - nothing random
Super Punch-Out!! leans a little harder on optimization, though the gap is small.
Shadow Warrior
Level routes, keys and secret knowledge reward study
Super Punch-Out!!
Memorising each boxer's tells and optimal counters is the game
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.
