Vaporware also includes announced products that are never released because of financial problems, or because the industry changes during its development. When 3D Realms first announced "Duke Nukem Forever" in 1997, the video game was early in its development. The company's previous game released in 1996, "Duke Nukem 3D", was a critical and financial success, and customer anticipation for its sequel was high. As personal computer hardware speeds improved at a rapid pace in the late 1990s, it created an "arms race" between companies in the video game industry, according to "Wired News". 3D Realms repeatedly moved the release date back over the next 12 years to add new, more advanced features. By the time 3D Realms went out of business in 2009 with the game still unreleased, "Duke Nukem Forever" had become synonymous with the word "vaporware" among industry writers. The game was revived and released in 2011. However, due to a 13-year period of fan anticipation and design changes in the industry, the game received a mostly negative reception from critics and fans.
