I agree that it was a Good Thing for them to make the platform more open (especially considering how different the hardware is), and the number of titles is impressive. It seems, however, that the average quality has fallen drastically. There's so much chaff out there that it's hard to pick out the good games. Most of the titles you see when browsing the aisles are laughable: My Pets (or something like that), myriad mini-game/puzzle games…it's just ridiculous how much garbage is out there for the DS and Wii.

That's not to say there aren't good games for the systems, there certainly are. It's just so hard to find them. I wish Nintendo had done something similar to what MS has done to support indie developers. It makes much more sense to offer indie games in the online marketplace than in brick and mortar stores. Cost of distribution is MUCH lower, and the average user has a much easier time finding quality, production house titles. Putting community ratings on the indie titles (that are almost completely unlikely to get reviewed by a major gaming site or mag) makes picking out the gems easier as well.

Granted, by doing it that way Nintendo can't make the claim of “over 930 titles for the DS”

Although the Moon game is for the DS. There are over 930 titles for the DS. That's getting up there with the old Playstation and Playstation 2.
