Due to various reasons (ranging from being of poor quality, being produced for a failed or soon-to-be-discontinued system or having its developer facing financial or legal woes), a game can end up being cancelled and cease production. Despite their status, concepts present in cancelled games can end up being reused in commercial releases and some cancelled games can end up being re-purposed into different projects. A game in development can also end up being vaporware, a term for projects that are announced on which development is started but, for a variety of reasons, were never published.
