Sure, I'll join in with the hype stuff.
64:
because Luigi,
because I really liked Metroid,
because I really like Star Fox and
because I'm apparently one of the few people who really likes F-Zero. Also Falcon Punch.
Melee:
because cool villain in general,
introduced a new franchise to the west that would later become one of my favorites and
because Mewtwo. I actually still remember that glorious moment when I unlocked it without being spoiled of its existence just after randomly playing the game for quite a while. (;n
Brawl:
who would become my main,
because Wario enough said,
cause DKC,
is Ike enough said,
I like because reasons,
because Pikmin,
is the ultimate unexpected character (;n
,
is one of my favorite sort-of villains (;n
, and
requires no explanation.
Sm4sh:
deserves mention despite not being a newcomer for being buffed A LOT,
was unexpected and looks like they could be fun,
and
are awesome for being in at all but
especially for the magic playstyle,
is one of my favorite franchises and him being in is AWESOME,
because reasons I'm feeling lazy and
I've warmed up to recently and I'm actually considering giving them a go in case they become one of my mains. I guess
(Shulk) because Xenoblade is one of my favorite games ever and
(jr) despite the oversaturation of Mario characters because... well, not Jr himself but more for Morton and Roy.
