Well, I think you may have answered your own internal doubts there so to speak
While the mention of a crack is not a bad idea per-se, the only thing that matters here to make this a reality is as you had alluded to in your response "availability of the crack for this type of a game".
In that, should there be a crack that does exist to remove said online/multiplayer components from the game, or if such a crack does not exist out of the box, will it be something that a modder can programmatically develop from the ground up to remove said online element of the game and then have it featured here on the Zone.
But realistically, it also boils down to how "
much" of the core game experience can be made accessible offline vs online. That is to say, assuming that much (if not all) of the core gameplay elements can be accessed offline and
online functionality is not needed, then it's not so much of a problem and an easier sell to have it featured on F95 Zone.
However, on the flip side,
presuming that online connectivity is a crucial part of the gameplay experience, then even if one were to introduce a crack, the game itself cannot be enjoyed to its fullest extent since the majority of the core gameplay experience can only be experienced via the online/multiplayer component, hence rendering the core gameplay elements quite uneventful, to say the least, and not so appropriate to then have featured on the Zone because users will not be able to get much out of the core gameplay experience.
P.S. Lastly, it may also depend on the popularity of the game being referenced here. And if it is not so popular/well-known of a game, then the likelihood of there being a crack to remove multiplayer and/or have a modder develop a crack from the ground might be slim, to say the least.
Not an impossibility, but an improbability if the game is not so well known in the fanbase or worth the effort i cracking to being with
