With Deus Ex : Invisible War nearing, I finally decided to sink my teeth into the original Deus Ex. The game has been a dream to play through. Even though the game is 3 years old, it has superior gameplay to most of today's gaming market.
The game not only requires reflex skills, but also strategic planning to accomplish your goals. There is also a role-playing element of the game, in which statistics decide the powers of your attacks. The AI is right in the sweet spot of dumb, but not too dumb. There are multiple pathways through each level, and several methods to any encounter. The game even features multiple endings.
Perhaps the only disappointment may be that the sequel will probably not live up to the original's glory.
