Show me where the Miis got a character before their games released. Show me where the Miis overtook long-standing series with millions of sales in the span of one game.

Because, with each game having an entirely new cast, we run into the problem where just having Marth in Smash means that 12+ games aren't being represented. Even with 8 fighters, we still don't have fighters from 2, 4, 5, 7, 8, 15, Warriors, TMS, etc.
