That's on my radar, it's a series I like to pick up once per generation because they are pretty fun. But for now I'm still going on Mario Kart and Smash Bros!
Yeah, we got MK8 with the Wii-U in a bundle, it's outstanding. We picked up the couple of additional circuits a month or so ago, waiting on the other two to be released (May I think?). It's in pretty constant rotation for family game night
Don't tell her, since it's additional birthday** surprises

, but we got her Smash Bros and Kirby (and a pack of colored stylus since the OEM one didn't even make it back to house from the Christmas trip). Also an extra Amiibo (Princess Peach ... you know, because she's a princess).
Mario Party is a blast - there's some skill, some luck, the new graphics are superb, the animations are terrific, it's got great design, a fun sense of humor, I'd say unless you're just a shoot-em-up type gamer, it's a must buy, especially to play with family, friends, etc.
** Also some books. Not e-books, no batteries, like actual paper, printed books to read.
