As letters. I hate HATE the monsters who pronounce it as a word.

As letters.

As letters when speaking in English, as words when in Finnish.

As letters, it sounds weird to pronounce them as words.

I've been thinking about this recently too, with the SNES Classic on the market. I've heard some people say Snes instead of ess-en-ee-ess. I've always pronounced all the letters but it's interesting to hear other interpretations.

Letters.

I also hate the word people. :P
Sounds weird... especially snes.

Probably a regional thing. I'm in Ontario Canada and everyone I know says it as letters. I never even heard it said as words until youtube.

Here in Spain we mostly pronounce it as words. I think I haven't met anyone here who spells the letters...

Always letters if saying it as such, though I would mostly just refer to them as Nintendo system or Super Nintendo.

Have never and will never say NES or SNES as a word.

I'm calling it Es.Ness. Fuck the police.

I just say each letter individually.

NES as a word sounds like “Ness” from EarthBound which makes things confusing, and “SUNESS” just sounds stupid.
