Game Cube was much better than the Wii because third parties would occasionally put in the effort. Sure, they all wound up getting ported to the PS2 but they were originally intended for the NGC.
The Wii is not for us. Nintendo effectively gave all of their past fans the finger. Nintards will clap their hands and wave spastically at the TV but Nintendo no longer needs their old fans. The old fans held Nintendo back because they just wound up going to the PS2 anyway. Soccer moms and grandmas are untapped cash reserves that are netting Nintendo billions of dollars in profit. Nintendo doesn't give a fuck about you and what you play, if there are three old decrepit fucks who will buy the latest Wii Sports for every one butthurt gamer they lose, Nintendo won't care. Which explains why there is barely any shit worth playing, despite having overwhelming dominance over the 360 and PS3 sales wise. We're barely blips on their radar, which is why they thought that we were getting treated by having a new Animal Crossing at E3 2008.
I do think the Wii is the worst top selling system of all time. Its library resembles something you'd see on failed systems like the 3DO, the Pippin, or WonderSwan Color. It has the shovelware of a top selling system without the classics that accompany it. Developers know, given sales of games like Dead Space, that it is more financially lucrative to make a mini game collection than anything else. Which is why we see more Ubi Petz and Jillian Michael's Fitness rather than Dead Space Extractions.
That said, I think Galaxy will be my favorite game of the generation. So for that game alone, to answer the question, I say yes. I kind of think this generation is kind of a wash but SMG is one of the few games that made me excited to play video games, at least for the month it took me to play and beat the game twice.
