Okay, I have to revise my opinion of Book 1 a bit. It looks like the new version has a lot of cut content, which I don't like.
It's a shame, I hope they add the original back in as well and give players a choice as to which they want to play. Luckily, I have several of my earlier GOG versions saved, so I can access the Book 1 in its original incarnations.
On a much more positive note, however, Book 5 was outstanding.
Anyone who was worried about important questions not being answered can rest assured that everything is wrapped up beautifully. There are a few minor loose ends, but all of the important questions are answered. I think those who waited had the right idea, as this will flow much better as one full game. Not that I regret playing each installment as it was released in the slightest.
I can now say for certain that Dreamfall Chapters is tied with the original TLJ as one of my two favorite games, which is the highest compliment I can give it. Point and click purists may disagree as it's not as puzzle heavy (though there are definitely puzzles), and the characters are controlled via direct control. (Personally, this has grown on me, since I can develop back pains when I use the mouse too much. I actually have a slight preference for this control method now.) The story and essence, however, are much more on par with the original than with Dreamfall. In fact, I'd go so far as to say the characters are generally more in depth, and Ragnar Tournquist has only improved as a writer with time.
I do hope that even if The Longest Journey Home is never made, he continues making adventure games at some point. (I see another genre is on the horizon first.) As far as I'm concerned, there will never be another series like this one.
