Normalfags have a hard time understanding video games because they have passive minds that only absorb and don't understand the idea of creating anything.
They see games as if they were movies, and think that modifying games is some kind of sin. They can't imagine video games as games per se. Imagine some faggot saying that you can't change the pieces on your chessboard, or can't create your own 3D models of the monsters in your tabletop RPG, or can't paint your RC cars... It makes no sense, but that's what the faggots who play videogames because marketing campaigns have convinced them that's what they should do with their free time believe.
