There's going to be some great games. There's certainly going to be a 1,000 different collections of mini-games for the system.
I think it's great for what it is, but I have about 0% in the thing. I'm just not looking to buy Mario-[insert sport or theme here] games much anymore. Still, there's plenty of people that want them and the old VC games...which is cool by me.
I liken it to cheap/run of the mill beer. It's usually something everyone can drink and enjoy, and it's fairly cheap. But, if you're buying something for a special occasion or your house, you'll probably get something a bit more complex and deep.
