Microsoft's Xbox CFO Dennis Durkin has claimed that the Xbox 360's first party games have been 'superior' to offerings from Nintendo and Sony.
Durkin told Industry Gamers that the likes of Forza and Fable have shown that Microsoft's console leads the likes of Wii and PS3.
"I would ask you to go and look at some of your data, just to compare first party performance over the course of this lifecycle, because I think our first party performance in terms of quality bars and units per title this shift has been superior to our competition's," said Durkin.
"…we think first party is an important tool and you can't dispute titles like Forza, which has consistently come out on a repeated cadence and sold multi-million units," he added
"You can't dispute things like Fable, which again, on a very consistent pace, has come out and sold 2 and 3 million units a pop. And now new titles, like Kinect Sports, which has come out and sold over 3 million units.
"So we are, not only building existing IP and incubating around titles like Halo and others, but really building new IP in new areas. And that's going to be core to us... to build those experiences and monetize those."
You can't blame a Microsoft man for backing Microsoft products above those of its rivals, but Zelda and Wii Sports fans, and those of Gran Turismo and Uncharted, might beg to differ.
It's not an argument that's likely to be settled any time soon.
