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 · Practiced Mastery
A martial arts career simulation and fighting game.

Optimization · Practiced Mastery
Sandbox warfare testing directional combat skill atop an optimisable army and trade economy.
Karate Master 2 Knock Down Blow leans Execution (Practiced Mastery); Mount & Blade leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Karate Master 2 Knock Down Blow
fighting mechanics need timing and reaction
Mount & Blade
Directional blocking and couched-lance timing demand real skill
Karate Master 2 Knock Down Blow leans a little harder on reads, though the gap is small.
Karate Master 2 Knock Down Blow
AI opponents follow fixed patterns, minor adaptation
Mount & Blade
AI lords and battle tactics are mappable scripts
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Karate Master 2 Knock Down Blow
match outcomes have some randomness
Mount & Blade
World events, prices and tournaments shuffle each campaign
Mount & Blade leans a little harder on optimization, though the gap is small.
Karate Master 2 Knock Down Blow
career training and build optimization matters
Mount & Blade
Army composition, trade economy and fief management drive conquest
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.
