Gone Home remains a great game to this day, but to fully appreciate its impact you need to understand the environment it originally released in. Back in 2013 you couldn't move for walking simulator-style horror games on the PC, with big companies and first-time developers alike using the resources at their disposal to make terrifying haunted house titles to satiate a booming audience.
And, on the surface, that was exactly what Gone Home was.
As soon as you boot the game up you're thrown into a spooky setting; an empty house, a stormy night, family members mysteriously missing and a bunch of puzzles that need to be figured out. However, the developers at Fullbright used this clichéd framing to hide the game's true story, which wasn't about supernatural goings ons or anything like that, but was rather a low-key family drama about a young girl coming to grips with her sexuality.
It subverts your expectations at every step, and uses your understanding of other games to pull the wool over your eyes.
