Wii Sports, and all stuff that surrounds it.

I'll begin by saying they're fantastic, intuitive and a good laugh. However here's my problem. 
It's not a game! It's an excersize machine. For example, you should never be out of breath whilst playing a game EVER. 
Game's should also have a campaign, or something similar. Is my campaign to reach pro level? If so that's boring. 
I can't think of anything that makes it a proper video game. I just can't. 
They're fun and a good waste of an afternoon but unless i wanna loose weight theres nothing for me.
