OP:
Are you kidding!? Nintendo is as much gaming as it gets. Maybe you are too young to get it but I grew up with NES and SNES. Nintendo and their classic series Mario, Zelda and Metroid are as "hardcore" as you can get! (I hate that term though)
Wii is still somewhat limited in the gamelibrary but I rather have one masterpiece like Super Mario Galaxy than 20 PS3 or 360 games. Of course it comes down to personal preference but one factor you can never take away from Nintendo is their fantastic history. The games that are available on Virtual Console is by themselves justifying a Wii console purchase.
Regarding DS I think the console has a fantastic library of games so I´m not sure what you critizise here? There is a truckload of terrefic games in all genres. Probably you have not tried out the games. I´d say that the DS library of games stands tall if you compare it with any other console.
