We’ve had it for a year+ and have about 300 cards for it. My wife enjoys playing with Freestyle mode by herself and we enjoy playing it together as a family. Management of the cards can become a pain. I guess my biggest concern with it is whether they’ll just turn the whole thing off after some certain date and we’ll be left with a pile of junk.
The base game comes with a limited number of cards. If you get it, you’ll end up wanting more cards. They’re not that expensive, but you probably can expect to end up spending at least $100 (vs. just $40) by the time you’ve picked up more cards.
