Trine 4: The Nightmare Prince is a welcome return for the franchise. It's arguably the best entry to date thanks to creative level design, gorgeous landscapes and excellent multiplayer. It may not be a new take on the formula like some expected, but considering the last time Frozenbyte tried that, perhaps this is for the best.
The Sojourn is an average, middle-of-the-road puzzler, that struggles to be memorable after the first few hours. There are interesting ideas here, both in terms of gameplay and aesthetic. However, they both suffer from the same problem, which is unfortunate repetition.
Blair Witch, much like the rest of the franchise, is a disappointment. It's not scary, it's rarely interesting and it's not particularly fun to play. It has a solid look, but is lacking in just about every other department. I say this begrudgingly, but you're better off watching the films.
