Let me tell you a little story.
Back when i was a kid (im 8 months younger than the Smash series itself), my father bought me a PS1 instead of a PS2 for some reason (maybe he just heard Playstation and forgot the 2) and he bought a bootleg disc of the Crash Bandicoot Trilogy (bootlegs were really common in my country, my father was......... protective of money to put it softly and it wasn't until 2013 that i managed to support the official releases) and that was the first exposure i had to Crash Bandicoot.
Later, my father also bought a Bootleg Disc that contained Wrath of Cortex, Twinsanity and Nitro Kart, and he later bought both the PS2 and Wii versions of Crash of the Titans that also were pirated (the first time i ever "double Dipped" on a game) and because of all this exposure, i became a Crash Fan.
Around 2010, i managed to play Brawl (again, a pirated version, and in this one i couldn't even play SSE or else a error message popped up) and i imagined Crash in Smash, and this was even BEFORE Smash 4 was announced in 2011.
That was the earliest moment in my life that i remember wishing for a newcomer, and as far as i remember it was the first time i ever did someting like that.
So there you go, Crash was the first character that i ever wanted in Smash. Needless to say, due to my desire to support the official releases since i was 13 has only grown much stronger so i HAD to get the N. Sane Trilogy, and it was the only game that REALLY made me have any interest in the PS4 at all, but since it was released on Switch i got that version.
Simon Belmont is my most wanted 3rd party (and my most wanted character in general), but after Bomberman's Assist reveal, the only other third party character that i have any interest nowadays is this little fella, since he was a childhood favorite of mine.
So you can put me in the support list.
