Does the differences between x-version and y-version of a game count as trivia?
Can you elaborate what you mean by X and Y? Are we talking about something like Pokemon?
That was meant to be an expression used in order to avoid giving especific examples.
Basically, what I meant was... any difference of any kind between the version of a game, really.
I would imagine so, considering they have a specific tag for it. When adding the trivia use the [Version Difference] tag and sub-tag [Console Difference].
