head to head
Mega Man: The Power BattlevsMetal Slug
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.
Mega Man: The Power Battle
Execution · Practiced Mastery
Arcade boss-rush testing pattern execution and weakness-order knowledge.
Metal Slug
Execution · Practiced Mastery
Twitch dodging and shooting layered over memorised arcade stage routes.
Mega Man: The Power Battle leans Execution (Practiced Mastery); Metal Slug leans Execution (Practiced Mastery).
Mega Man: The Power BattleMetal Slug
Axis by axis
Execution7 vs 8
Metal Slug leans a little harder on execution, though the gap is small.
Mega Man: The Power Battle
Boss pattern dodging at arcade pace tests the hands
Metal Slug
Dodging dense bullet patterns and precise shots carry every credit
Reads0 vs 0
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Mega Man: The Power Battle
Robot Masters cycle fixed movesets
Metal Slug
Enemies follow fixed arcade scripts, never adapt
Variance1 vs 1
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Mega Man: The Power Battle
Boss selection order barely changes the run
Metal Slug
Spawns are nearly deterministic once a stage is learned
Optimization6 vs 6
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Mega Man: The Power Battle
Weapon-weakness ordering is a solvable puzzle
Metal Slug
One-credit clears come from memorising routes and spawn patterns
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.
