Which should I get for Wii? Super Mario Galaxy or Super Mario Galaxy 2?

I'm going to get a wii soon, and I'm wondering which is better, Super Mario Galaxy or Super Mario Galaxy 2. I keep finding good reviews for both, but nothing that compares the two. Please no 'get both' answers, I only have enough money to get one or the other. And please explain your choice! ... show more I'm going to get a wii soon, and I'm wondering which is better, Super Mario Galaxy or Super Mario Galaxy 2.
