I am currently thinking of switching from Mutants and Masterminds to hero. Mainly because when I'm doing stuff in M+M I find myself thinking hero could do this better. And have realised that it will be a lot easer to import some of what I like about M+M into hero rather than the other way round. Im having my first full read of the 6th edition rules, which is a slow process for me as im dyslexic and they are big books.
Anyway to bring this back on topic, one Idea i might 'borrow' from M+M is the feature power. This cost 1 point in M+M, I'd probably price it it 3 (maybe 5) in hero.
This just gives a feature that provides some minor benefit. So a character might have 'feature - thick fur'. Which would give a bonus to resist cokd environments, but fall short of full life support.
If I wanted to price it at all A car could have 'feature - headlights, feature - dark/light sensor'. 6 points job done. But I,d probably just assume a car had lights as standard.
