These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Ensemble Darkhorse: While he maybe seen as a joke now by a majority (including Capcom themselves), Captain Sawada is fondly remembered by those who've played the console version, thanks to his revamped moveset.
"Funny Aneurysm" Moment: In M. Bison's ending, his rule is described as spreading "like a cancer". Considering that it was well known that Raul Julia had cancer at the time...
Narm Charm: If you and your opponent get into a throwing war, counter your opponent's throws enough to hear "SLAMMASTER!!!". It's undoubtedly goofy but still a fun soundbyte.
Older Than They Think: The arcade version was the first game to give Vega a multiple flip kick Super Combo, which became a standard part of his movelist in other games starting with Street Fighter Alpha 3.
Honda's Super Shiko special move in the arcade version became the Shikofumi command move in Street Fighter IV.
The Problem with Licensed Games: While the arcade version of is pretty terrible, fans were surprised to find that the console version was actually a pretty decent game, since it played more like an actual Street Fighter game. It was also the first game in the series to feature EX Attacks, which would make it into the proper series and become a pretty important part of the gameplay in games they're included in.
