whats wrong with that. this is aimed at the new gamer so why not.I like the idea of unlocking some characters in SSE, but I don't like the idea of them all being unlocked through it. One of the things I liked about Melee was that there was a wide variety of ways of unlocking the different characters, and it was much more down to chance than anything else. For example, to get Luigi you had to finish the first stage of Adventure mode with "2" as the last digit in the timer. Who would consider specifically trying that without being told first? The alternate methods involving hours and matches played in VS seemed to be more aimed at people who preferred multi-player (apart from Mewtwo).
If all the characters were unlocked in SSE it would just be too easy and linear. You'd know that if you carried on playing it eventually you'd get every character.
