Possibly the most-delayed video game in history is finally available on the Game Boy Advance

Making a video game on any platform takes hard work, and even if a game is finished it's still not immune to delays (see: Duke Nukem Forever, L.A. Noire and Diablo III.) A group of Italian programmers had to wait 22 years to finally see the release of their fantasy hack'n slasher Kien for the Game Boy Advance (GBA) -- a console whose last units went into production in 2009. Kien first started its long development in 2002. A small group of Italian programmers formed AgeOfGames, the first company in the country to start production on a GBA title. Two years later, they had a finished product, but the game never saw store shelves because its publisher deemed it too much of a financial risk to release.
