it is scary at the beginning, but definitely is too fun to learn all advanced stuff, Samus is a good starter since is not too fast and has a lot of tricks to learn, then you can jump to faster characters
It's not that I just had no desire to learn those technical nuances just to be able to compete and probably still be a pot monster. It wasn't rewarding.
The thing is for your average player, Fox/Falco really don't require any more inputs then any other character (i.e. baby bullets lol), that's something only competitive players will notice.
I'm speaking as a competive player of course but yeah you're right.
