BP, as stated in the article, the list is all games from a given publisher at the time of writing. So there's a pretty good number of real games there, with the largest number being from Capcom (with both the highest number and the highest percentage of good games, though admittedly this is largely due to a good number of ports of quality last-gen titles), followed by Sega, Konami, and Namco (where you feel those three companies fall depends on your feelings toward some of the more prominent non-shovelware games in their respective catalogs).
The repeated complaints about rail shooters in that article show nothing more than a personal disdain for a genre that actually works great on the platform. Disregarding good games as "stuff" (as done in the Capcom section) is misrepresentation as well.
All of Activision's games there that could be considered "good" are multiplatform and better on the HD platforms. EA at least has the Boom Blox games to save them from that problem.
I'd like to see this expanded with some of the other third-party companies, even the ones who only have one or two titles on the platform. I'd also like to see it brought up-to-date for the companies already represented.
I'd also like to see the same done for the DS and, for fairness, the other three platforms this generation (because even though the Wii looks so bad in terms of third-party shovelware, Sony's platforms and the 360 aren't free of the stuff by any means).
The comment about Nintendo's NES-era policy is funny.
