It's hard to call Dear Esther a game, as the player makes literally no interaction with their environment, all they do is simply walk through it and look around.
Every once in awhile the narrator will speak about random things when you eventually reach the next trigger (at a tediously slow walking pace I might add). While this is supposed to help you understand the story, the simple fact is that the "story" is left so incredibly vague that it's somewhat pointless to attempt to figure it out, as there's no right answer. Sometimes this works for games, but in Dear Esther's case, the game does a poor job at getting the player invested in the story, and considering nothing about it is for sure, the player isn't able to piece together some kind of answer like in other vague stories, as you can't rule out any possible conclusion. There are also no meaningful, developed characters in it, rather you're told a collection of names and left to come up with who they could be on your own.
The writing reminds me of some teenager trying to write "deep" poetry for the sake of being deep. The narration snippets are told in a boring, artificially drawn out fashion, much like the game itself is. You'll dread backtracking from one of the many pointless, long dead ends so much that you'll probably noclip to get back to your previous location faster.
So is there anything good about this game? Yeah, it's pretty, and has a good soundtrack, that's about it. Not nearly enough to justify the $10 price tag.
I see this game compared to The Stanley Parable often (which made me look forward to trying this out), but the big difference between that and Dear Esther is that the player's actions actually matter in The Stanley Parable. The player has no purpose in Dear Esther, they're pretty much just moving the camera through scenery for the entire game. All I can say is, I'm glad I didn't pay for this "game", even $2.49 would be stretching it to me. You can find equally great scenery and far better story telling in games with actual gameplay.
