I've never really understood this phenomenon. I don't think I've ever become angry enough to destroy any of my things, much less game stuff. When a game is tough or is cheap, then I enjoy overcoming ridiculous difficulty or cheapass things (ie; Ninja Gaiden bats). The physical cartridge, system, or controller could not care less what is done to it. It doesn't have a mind, emotions, or pride.
That said, I've already admitted to (lightly) trashing some arcade games in the past (which came back to haunt me later in life), but they weren't mine. They belonged to someone else, and that makes it okay.
