The only reason to buy this game is its cheap price. However, just because it's cheap doesn't mean it's good.
First things first, this game is not scary. At first Home feels eerie, but you'll soon come to realize that there is absolutely no threat in this game. Like, at all. There is absolutely nothing out there that can hurt you. The only time I ever got scared while playing Home was because one of the sound effects was way too loud. Other than that, there is nothing that should even remotely scare you in the game.
Home is basically a game where you walk around, pick up stuff, and read in-game text. To mix things up, there are also a couple of puzzles that are fairly easy to solve. Home ends in various ways depending on what you do and what items you pick up throughout the game. So if you pick up weapons thinking that you might encounter some threat, you're going to get an ending that you probably don't want.
And speaking of endings, they're dumb. I'm not going to reveal my ending, but mine just didn't even make sense. I literally facepalmed and shook my head after only "playing" the game for an hour, beating it, and then getting that ending. After this happened, I decided to go out and read other people's endings to see if they were as bad as mine. They too, are dumb. Every ending I read either didn't make sense or was just straight up ♥♥♥♥♥♥♥♥. Or both.
Just doing one simple thing can get you a dramatically different ending. This is usually a good thing for games with different endings, but the differences in Home are WAY too huge. They're night and day type differences for some choices. Usually for an ending to be so different you have to do a lot different from your previous playthrough. In Home, however, one change in the right spot completely alters the ending. Some people might play through the game a few times just to see what endings you get, but I usually don't do that. Reading suffices.
Personally, I was fine with paying a few bucks for something so dumb. I'll play anything, and I would actually recommend getting this if you're bored as crap and want something dumb to play for an hour. But if you're a serious gamer that wants something good for the money, don't get it.
