As the spiritual successor to Wii Fit, Fitness Boxing has–naturally–flown under the radar. Its release seems to have been aimed at cashing in on those of us who are looking to start off 2019 with a workout routine or, at least, some way to justify our "new year, new me" attitude. But now that reviews are coming in and people are getting the chance to experience the game, there's one thing that's seemed to slip our minds: Fitness Boxing is rated "T" for "Teen."
According to the Entertainment Software Rating Board (ESRB), that's because the game features "Suggestive Themes," or more specifically, because "all of the female characters have breast physics incorporated into their movements; their breasts frequently jiggle/bounce in a noticeable manner during stretching and boxing routines."
Boobs, bosom, breasts, we all have them, and, almost everyone has had their mouth on one in their life. They're so ingrained into the very fabric of life, and yet, a boxing game that's intended to encourage people to exercise is deemed an inappropriate place to have them move.
It's unclear why developer Imagineer decided to include breast physics, but it could just be so that women could see a reflection of themselves in the game's four female fitness instructors.
