While I agree with the fact that the ambiguous title makes it seem like an obvious duplicate, the first question is really asking what the 32- to 64-bit conversion of the remastered edition means for the game itself. Because of this, I disagree with the VTCs based on duplication of the second question.
However, the question of what 32- to 64-bit conversion means for a game has been asked before, but for a different game.
Namely, this question about Transistor
Would this question count as a duplicate of the Transistor question since both are asking the same core question or would it be valid since it is about a different game?
