Released in 2000, Deus Ex is the best game ever made in the history of PC Gaming. It deserves more than Half-Life or any other game, as the game has a rich storyline and decent gameplay.
Warren Spector came up with the idea of making Deus Ex in 1994 while he was working for Origin Systems. The original conception was entitled Troubleshooter. He thought the game would never finish due to the lack of money at Looking Glass, but John Romero and Ion Storm came along and said, “Make the game of your dreams. No limits.” It took him about two nanoseconds to say “Yes!”
The Singleplayer delivers action, adventure, RPG, hacking, immersive simulation, and stealth.
Deus Ex is known for its higher replay value, conspiracy theme/story, and gameplay.
I replay the game at least twice a year. It has been so enjoyable ever since I bought a retail version many years ago. The game offers more than one choice to complete an objective. It is not like go from A to B. You can use maximum lethal weapons if you want to go the way of a killer or use non-lethal weapons if you want to be a pacifist. The world is detailed with many interesting characters, backstories, agendas, etc. There are always multiple solutions to one objective, so all these things make Deus Ex a unique game.
The modding community is unique because of all the hard work people have been doing in making the game better. There have been many good SP and MP mods, and there is a good amount of custom creations by the community.
There is a huge amount of custom maps, as well as many new tools/utilities, and weapons.
The game deserves much more attention in Multiplayer and many players should try out the RPG, fun, augmentations, and other types of servers.
