Possessive usage

Should the bold words be possessive or plural? Thanks.

“Anything short of perfection would upset the Zelda enthusiast; however, aficionados definitions of “perfect” are far from analogous.”

It should be:

“Anything short of perfection would upset the Zelda enthusiast; however, aficionados’ definitions of “perfect” are far from analogous.”

The sentence describes the definitions of more than one aficionado, and the plural possesive of aficionado is aficionados’

It should be:

“Anything short of perfection would upset the Zelda enthusiast; however, aficionados’ definitions of “perfect” are far from analogous.”

It’s a possesive plural, like “…better than her classmates’ grades”, for example.

Since the OP has been answered twice, ably, I’m going to comment on the rest of the sentence.

Analogous to what? Each other? They should be identical if they’re truly “perfect”*, although I suspect that’s the point you’re trying to make. Why not just say that outright? Perhaps something like “afficionados disagree on the definition of perfection” or “afficionados disagree on the aspects needed for game[or whatever] perfection”. In any case, the use of “analogous” there really bothers me.

*We’ve already had a thread and a pitting on the definition of “perfect”, so let’s not go there again.
