All I can say is, that there is no sufficiently enough prepared data to use to give a definite answer.
However, asking the people here about their peferences is bound to give wrong results, as we are enthusiasts and therefore do not correspond to the average.
My feelings tell me that there is some truth to it though, at least across all games.
I expect certain genres to sell close enough to the competition that these sales can be considered equal
And then I expect there to be genres which sell much worse... not only relative to the install base, but also in absolute numbers.
So yeah.. I believe that this statement is true for some types of games and false for others.
I do also think however, that, barring 1st party games, there are no categories of games that sell better on a Nintendo system than on others.
