Gameplay resembles a combination of Apples to Apples and Balderdash, but, in my opinion, Dixit is a much better game. It's a fun and unique challenge. The artwork is gorgeous. Everyone I've played with seems to love this game. Also, you don't just have to take my word for it. Dixit was recently awarded the coveted Spiel des Jahres award, so the Germans like it too.
If you want more Dixit cards (as I expect you eventually will), you can get them through an expansion pack.
UPDATE: There is now a third Dixit set: Dixit Odyssey. It is not just an expansion pack. It includes 84 more cards, a board, and all the necessary tokens. The rules has have been slightly tweaked, and there are also now variant rules that allow for, up to 12 players to play, either in Team variation or a streamlined Party variation. The box is big enough to hold the cards from all three Dixit games.
It's been over a year since I first played Dixit, and I still get excited about playing it. I think Dixit is destined to be one of those classic, mainstay games.
