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 · Pure Mechanics
An explosively destructible run-and-gun starring parody action-movie heroes.

Execution · Pure Mechanics
An arcade test of jump timing and enemy-flipping precision on a single screen.
Broforce leans Execution (Pure Mechanics); Mario Bros. leans Execution (Pure Mechanics).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Broforce
Run-and-gun reflexes amid constant explosions
Mario Bros.
Precise jumps and bump timing under crowding enemies decide survival
Mario Bros. leans a little harder on reads, though the gap is small.
Broforce
Enemies are dumb scripts
Mario Bros.
Versus mode adds light human interference, enemies are scripted
Broforce leans a little harder on variance, though the gap is small.
Broforce
Random bro assignments and destructible chaos shake runs
Mario Bros.
Enemy spawns vary slightly but patterns are quickly learned
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Broforce
Knowing each bro's kit and level layouts helps
Mario Bros.
POW block usage and enemy routing have known best lines
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.
