> They're not means at all, they're the percentage of positive reviews. dnd games as you've identified them, the reviews are ~93% positive, and the nondnd games as you've identified them are ~90% positive. So I think your point that there's not much difference is well born out, if % positive reviews is the metric

Ahh I see, yes positive% is a good idea, thanks. But mashing them all together like that ... sure, why not, it's another angle on this, but it loses a lot of detail, as destructive aggregation usually does. Important detail too, as these games are difficult to directly compare to each other.
