Gameplay is how a computer game or video game actually plays: what you do, what skills you need, and how the design makes that feel. It is not the pictures, the music, or the story, though those sit next to it. People say “the gameplay is good” when moving, fighting, solving, or building feels fair and fun. Reviewers and players use it all the time; it is normal talk in that world, not a school word. Though actually, people stretch it a bit: they may say “gameplay” for one mode, or even for “the way this whole thing works,” not only video games. The core idea stays the same: the doing, not the wrapping.
