Anime/Visual Novel: Air
Air is a Japanese adult visual novel developed by Key.
Kyoto Animation produced a 13-episode anime television series and a two-episode anime mini-series in 2005, and Toei Animation produced an anime film in 2005. The anime adaptations are licensed by Funimation who released them in North America.

Air was described as a game that stands out, much like Key's first title Kanon, due to an intricate plot that keeps the player interested, and has a good replay value as well.

In an interview of Jun Maeda and Yūichi Suzumoto, they were both surprised to find out that the Japanese public (in March 2001) felt Air to be a soothing game, but Maeda and Suzumoto made it clear that this impression is completely at odds with their impression of the game, and they remark that there was not one person who worked on Air who thought that.

I haven't played the game. I did like the anime, but at the moment don't understand it as well others do. I do recommend checking out the anime for yourself. It has a lovely soundtrack and interesting story.
