For those who want all the characters unlocked from the get go, or they just can't get that specific character because it's too tough and give up, how about giving them the option to type in a specific button code on the title screen (typing it correctly will give the same result as pressing start) and BAM, all the characters available and ready for whatever. As well as a separate code for all stages unlocked. Providing the codes on a word file.
I'd also like the options to erase the hidden characters and stages like in 64 and Melee. Giving us the ability to unlock them all over again, either the old fashion way, or by the button codes.
Don't have all the characters simple to unlock though, like beating A with B. I'd like a challenge when unlocking some of them but not have them taxing on time. Getting them all should take no longer than 8 hours if one knows how to unlock them all but is starting the game for the first time.
As for the hidden characters themselves. These are the options I hope for:
-50% starter/50% hidden (what I really want)
-51% starter/49% hidden if roster is odd numbered
-40% are hidden
-30% are hidden
-Only the original 8 as starters
-Only the characters playable in an official Smash are starters
-Only Nintendo characters are starters (Klonoa just screams hidden for me)
