I just finished playing Dear Esther. It’s a fantastic title and I suggest you pick it up on Steam. I’ve embedded a small slideshow of screenshots I took whilst playing. Don’t worry, no spoilers. Also: it looks 10 times better in motion.
There’s only one thing I would have liked to have seen in Dear Esther: an option to turn down/off the music. I love atmospheric games like this and realMYST, and part of the magic is just soaking in the environment. It’s hard to do with an orchestra playing.
That being said the music was wonderful and I bought the soundtrack to listen to it later.
