Though old forests are rarely inspired by theme park rides, horror movies, folk tales and dreams (they more or less simply just grow, you see), successful gaming forest usually are. Or at least Heartwood is and you should probably set a few quality minutes aside and go explore it. It's creepy, audio-visually beautiful and even partly inspired by actual forests. It is also available for Windows and Mac, while an Oculus Rift version should also eventually happen.
