Mega Man Zero
Cyber-elf locations hidden at first
Red Dead Redemption 2

Mega Man Zero
Rank system penalises elf use, rewarding optimised clean runs
Red Dead Redemption 2
Loadouts and routes solvable but loose.
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.
