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.
Hilarious in Hindsight: Pagan's Medusa Fatality would be seen again, but this time in Mortal Kombat 9, by Kratos(as an added bonus, consider the fact that it's wielded by a character who kills Gods, which is exactly what the original did since all of the characters are Gods!)
Speaking of Mortal Kombat 9, it seems that Jax finally gained Tak's Football Kick Fatality too.
And now, with Kotal Kahn's reveal in Mortal Kombat X, we have a moment as one of his styles is called "War God".
Narm: From its kitchen-sink character designs to its odd combination of digitized sprites in a 3D game (making the characters resemble paper cutouts when the camera shifts) to its desperation to be a dark game (the announcer goes more over the top with "FATALITY!" than any MK game).
Obvious Beta: Even Midway was upfront about the game being a testing ground for Mortal Kombat 4.
