Let's be straight - Gone Home is a visual novel. Japan has a ton of 'games' that amount to navigating and talking to people and basically reading your way through a story, and I wouldn't really consider those to be games either.

The very essence of a game is the ability to make interesting choices, so while something may be story-driven and interactive and 3D and be sold in Steam, it doesn't necessarily make it a game.

I will concede that people have difference definitions of what a game is, and this is mine. If you have a different one, let's hear it.
