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.
YMMV: Mega Man 6
Anti-Climax Boss: Even by the game's standards, the Wily Machine is embarrassingly easy to defeat. The fact that all of its forms are weak to the Silver Tomahawk doesn't help its case.
Some hardcore fans like to consider 6 to be the final game of the Mega Man Classic timeline, since it is the last of the NES era Mega Man games, ignoring the events of Mega Man 7 and beyond (or skipping directly from this game to 9, as 9 starts with Wily having been captured for a while).
Some fans like to play around with the idea that Mr. X is/was a real person, and that Dr. Wily either kidnapped him to take his place for the tournament, or that Dr. Wily actually killed him.
