Not so much a game as a semi-interactive ghost story in a beautiful, Source-powered landscape, Dear Esther is worth playing… so long as it’s on sale. The gameplay’s not long enough to justify a £6.99 price tag, and there’s almost no challenge at all in the gradual exploration of a Hebredian island and of the mind of the story’s narrator… but it’s still a great story.
Play it slowly. Take your time. Turn the lights off and have a glass of wine with this game. Make sure that you keep your eye on the screen, because there are incredibly subtle and short-lived elements that appear for moments, and then are gone.
But do play it. At least: if you can get it on sale.
