Deus Ex is the rare combination of several genres, real-life conspiracies, loads of content to explore, and captivating environments.
The game was also highly ambitious, with development spanning several years. Not only are there plenty of cut concepts, but also plenty of concept art and screenshots from early versions of the game. The released game also contains slews of cut conversations, loads of unused textures, and some tidbits from cut levels.
