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.
Contemptible Cover: The original SNES port features a cover that is naught but a blank background and an extreme close-up shot of Haggar and a burly Leatherman thug, possibly meant to be Abigail, eyeballing each other. It sends a somewhat different message of what the game is about than Capcom USA probably intended.
Poison. Fans wanted her to cross to the Street Fighter series so badly, they kept asking producers to put her in the games.
Rolento.
Epileptic Trees: Thanks to an official artwork of Lucia doing aerobics with Chun-Li, the fact that both are detectives, and the resemblance of her moves to Chun-Li's signature Hyakuretsu Kyaku, it's been implied that Lucia may have trained under Chun-Li or is even friends with her.
Final Fight: The mayor's daughter is kidnapped by a gang. The mayor, an already retired pro wrestler, enlists his daughter's boyfriend and his friend, and kick ass and take names.
Final Fight 2: The mayor's friend's fiancee and master were kidnapped by another gang, and he's joined by his friend's future sister-in-law and a martial artist. They kick ass and take names.
Final Fight 3: A gang war erupts in the city. The mayor's friend is back, and they're joined by a cop and a mysterious drifter out for revenge. They kick ass and take names.
Launcher of a Thousand Ships: Although Guy is canonically married to Rena, he was paired with Maki (Rena's younger sister and Guy's rival for the Bushin-ryu succession) Rose, and Ibuki, among others.
Porting Disaster: The SNES port of the first game was a borderline case. In terms of sound and graphics it was very close to what the arcade game offered (some even prefer the SNES soundtrack over the arcade original, which used rather harsh instrumentation). On the other hand, Guy (or Cody, depending on the version) was missing in action, there was no two-player mode, one of the levels was left out, and there were generally fewer enemies on the screen at any given time than there were in the arcade version, which messed up the game's balance somewhat. The bowdlerization didn't really help either.
