head to head
Mega ManvsMetal Slug
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.
Mega Man
Execution · Practiced Mastery
Demanding platform execution plus a solvable boss-weakness ordering puzzle.
Metal Slug
Execution · Practiced Mastery
Twitch dodging and shooting layered over memorised arcade stage routes.
Mega Man leans Execution (Practiced Mastery); Metal Slug leans Execution (Practiced Mastery).
Mega ManMetal Slug
Axis by axis
Execution8 vs 8
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Mega Man
Pixel-precise jumps and shots against brutal fixed stages
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
Robot Masters cycle rigid scripted patterns
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
Nothing changes between attempts
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
Boss-order weakness routing is a known solvable layer
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.
