Nintendo never really had those games under its belt though, did it? I mean, it got some for sure, but it was never the hook or reliable or anything; if you wanted the best version of those shooter and sports games experiences, you went on other systems.
If you care for those games, the solution is just to get money and have multiple systems. *shrug*
As far as the GamePad goes, it's pretty useful, but like someone said, not always available. The quality also isn't HD, it's like a dimmer 480p, and of course the screen is tiny compared to a big TV, so yeah. I personally enjoy it since I can play in my room and there's the potential for playing mature games solely on it, but it's not like you can take it anywhere in your house and get a nearly identical experience to playing on the TV, it's more of an alternative back-up/bonus of sorts
