Voting is meant to separate good from bad answers. However, identify-this-game questions can only have one correct answer or none. There is no (potential) continuous answer quality level.
So, should voting be based on probability of it being the correct answer, which is indeed a quality of the answer, while they can still be wrong answers to the actual question.
In the end, we have answers of varying quality and voting levels, while there may actually only be one valid answer or none. This is kind of a gap, at least compared to other answers where there may be multiple correct, but slightly different answers.
On a broader view: Should such questions be even here?
