Terri, it's a continuation of Dreamfall, but with no combat and hardly any stealth. There is one stealth section in Book 2 I could have done without, but other than that, it's played like a regular adventure game with some large, open areas. It's very rich and detailed, more like the original TLJ in that regard, so it almost feels like a combination of both games. It also adds a choice and consequence element, which seems to be very popular in adventure games now. The original games had this to an extent, but it is much more emphasized in Chapters. They were obviously inspired by TellTale, but Chapters has far more exploration and optional character conversations, making it longer and more complex than a TellTale game. Also, I think it's perhaps the most beautiful game I've played, even more so now that they've upgrading their engine. The controls are more like Dreamfall's, but a bit better implemented, so if you played and enjoyed that game, you shouldn't have any problems with them.
The story and characters are fantastic, as per usual with these games.
Zoe and Kian both receive a lot of character development, and both feel more complex than when they were first introduced in Dreamfall.
The puzzles are all right. There are some good ones, particularly one involving bots in Book 3. They're better than Dreamfall's puzzles, but not as difficult as the classic puzzles in TLJ.
As a total experience, I think this is one of the best games I've played. Everyone will have a different opinion, of course, but for me, this is almost up there with the original TLJ. Considering that game pretty much can't be topped on my personal list, that's saying something.
