The Longest Journey takes apparently 17 years, because that is the time span between the release of the original game in 1999 and the last game of the series in 2016, which finally finished the story. The Longest Journey is a classic point and click adventure game, meaning it has a wonderful story and world but sometimes really, really, REALLY stupid puzzles. But luckily only sometimes, often they are both entertaining and brain teasing, but you should still keep a guide nearby to not get frustrated.
