the doa1 booklet (ps, pal) states that gen fu had left china in 1976. this is the only time (as far as i know) that an actual date was mentioned... like they always talk about months and days but never the years. i find this detail way more interesting than it probably is.
i wish the damsel in distress in the first super mario was rosalina, so she would be the video game icon peach is today. she would be a way better role model than peach, who basically depends on like everybody. the problem with that is that this wouldn't be possible since rosalina would kick bowser's ass before he could even think about kidnapping her.
waluigi really shouldn't be in smash in my opinion. no real moveset potential, no appearance in a main game. even if he would be included, most people would drop him after a week or two. he's more like a meme than actually a valuable character.
