Yeah. You think the guy who says that first line is going to spell out S.N.E.S. instead of saying "Snez?"
In my experience, the people who actually owned the SNES when it was new just called it "Super Nintendo." The NES was a "Nintendo." And in fact, playing video games on a console at home (as opposed to at the arcade) was often just called "playing Nintendo" regardless of which system you had. People "played Nintendo" on Sega just as sure as people drank "a Coke" that was a Pepsi, or used "a Kleenex" or a "Q-Tip" that was any other brand.
Years later, when the next generation started to do some retro gaming, they were the ones who started using an abbreviation instead of calling it the "Super Nintendo." They called it the "Snez." Neither group said S.N.E.S. because if you're wanting something shorter to say than "Super Nintendo" (5 syllables) why would you shorten it to S.N.E.S. (4 syllables) when you *could* just shorten it to "Snez" (1 syllable)? That'd be dumb. That'd be like deciding you don't want to pronounce all of All Terrain Armored Transport, so you shorten it to A.T.A.T. when you *could* just shorten it to At-At. DUMB.
