> One explanation for why this game works is that there is only one way in which things are related, and this comes from the underlying world we live in.
I think what this might be trying to say is something more like: ...there are many ways in which things can be related, but those relationships come from the underlying world we live in.
I.e. there are obviously many ways in which things can be related, but if we assume the quote is not entirely counterfactual, then it must be getting at something else. I suppose "way" here is being used in a different sense, but it isn't clear.
