Gone Home is a difficult experience to describe, especially when it comes to recommending it to someone else. It's an interactive short story, and I do mean short. The script for the written notes and spoken dialog probably wouldn't amount to more than 10 pages. The characters are very broadly sketched with only the smallest hints of depth and complexity. The focus of the narrative is a really pretty mundane love story which presents little in the way of surprise.
What Gone Home does well though is provide a powerful injection of 100% pure, high grade nostalgia directly into the bloodstream. Nostalgia both for childhood and adolescence in general and the 1990s in particular. A story for the ages this is not. A story for people who were teenagers in 1995? Yes. Maybe.
The writing is good and the voice actor who played Sam did an excellent job. That, coupled with the introspective and tender mood, is enough to carry you through at least one playthrough (80 minutes for me). That said, there's certainly no reason to play again. In fact, when you start looking back over the experience you begin to resent the numerous red herrings whose sole purpose seemed to be to obscure the real focus of the story for as long as possible.
In the end I found Gone Home to be atmospheric and touching in a simplistic way, but also fundamentally shallow. The asking price of $19.99 is way, way too high. I'd recommend purchasing only when a big sale comes along, and then only if you're a fan of this genre of entertainment.
