I think it helps if you stop making unnecessary distinctions. I have purchased about 8 retail and alot of ware games this year. All enjoyable. Two are first party. Why is it imperative that Nintendo has to provide a torrent of games when I can get my fix from various providers?
Well, simple...
Third party software on the Wii is, by and large, a waste of time. I would much rather play such games on a more powerful platform and, unless the game is of extremely high quality, I will simply avoid Wii third party releases. Nintendo, on the other hand, will only release games for the Wii console (obviously) and, as such, I would actually like to see some effort placed into software fans of traditional game titles might enjoy. Nintendo is capable of making incredible software, but most of their internal development seems to be focused on casual titles (the "Wii--" series) or mediocre sequels to already uninteresting Gamecube titles (Battalion War 2, Mario Kart, Mario Party, Animal Crossing, Mario sports titles, etc). Mario Galaxy, Metroid Prime 3, and Smash Bros are their best efforts thus far. Considering the machine was released in 2006 and it is now 2009, the lack of high quality Nintendo software is a bit of a drag.
Of course, I'm well aware that you don't feel that way and have different standards, so I wouldn't expect agreement. That's simply my point of view on the matter.
