I got it today! Only lv6 so far but it's really fun. I like how much choice you're given over what to do and when to do it.

I will probably get the expansion pack when I've finished the main game. Too bad you can't play together if you don't all have either the DLC installed (in fact, I read it's only 2 blocks so it's already on the cart, what is this, Mass Effect?) or not.

My friend code is 2878 9582 0915 if you want to play together sometime. (I'll make a new post when I get the DLC.)
