There is truth to that, but if you look at the big picture, sony first party titles do sell well. There is the obvious Gran Turismo which is one of the biggest franchises in all of gaming, God of War is a solid seller. And even the more out there titles do well, I mean LBP outsold Metroid Prime 3 so its obviously able to move the units if it can beat one of nintendos biggest franchises. There is plenty of other examples as well, Uncharted, resistance, killzone, ratchet and Jak. They may not be able to outsell Mario and Zelda but then again very little can. However they still sell really well. In fact the only sony titles that don't sell that well are the Team Ico games, and they are there for style points anyway.

Sony actually has a decent amount of games that don't sell well. Genji, Lair, Folklore, The Eye of Judgment, and the NBA games all have low sales for the development costs they likely needed. Even so, that is a pretty small collection of games so far this gen.

BTW, Shadow of the Colossus did pretty decently actually.

I find this assertion that Sony doesn't market its games puzzling. I've had more exposure to PS3 marketing than any other current-gen console. LBP and KZ2 were particularly heavily supported.

If I were to fault Sony marketing, it would be for all the advertising pushing the hardware itself or the Playstation brand instead of particular software. People aren't going to buy your hardware just because you made it shiny and black.

Looking at Sony's performance as a publisher, they definitely have some problems, though. They have a huge studio investment, but they clock in way down at 7 or 8 in annual sales in NA and Japan (annual sales aren't available for Others, but I don't expect they're higher than fifth amongst EU publishers). In 2008, THQ sold more software in NA than Sony did. That can't be good.
