Not being able to make satirical comments about any game-related material would mean nobody could say something like, "Controlling Iron Man feels like fighting Jarvis for control of the suit", or "Storm is as effective as a light breeze"
My understanding is that Digital Foundry type of performance review is fine, but comments on how the control feels laggy or the game is a lower-tier copycat of Overwatch are not okay.
In the context of a game, let's say a clearly outdated graphics engine that everyone can agree on looks very dated. Or game-stopping bugs. Constant crashes. Etc.
