I couldn't find this question asked before even though it seems like an important decision to me: How do we tag a question that may or may not have different answers depending on platform? The most recent relevant multiplatform game of note is The Legend of Zelda: Breath of the Wild which came out simultaneously on Wii U and the Nintendo Switch.
From observation, it appears that we don't include a console tag if the question isn't console-specific which, since this particular game is a direct port as far as I know, is usually the case. However, there are some questions like this one about save files that could potentially be console-specific, yet happens to have the same answer for both consoles. Should we include both console tags if the answer works either way, remove the tag because that's our convention, or leave it as is because of the original intent of the question and answer?
