Deus Ex was probably the greatest first person shooter I have ever played (and that includes Fallout 3). It stuck to the norms of its genre while simultaneously creating the trend that would be followed by many games in the future. It was the forerunner of the amazing variety of FPSs we have today. The third game in the series, Deus Ex: Human Revolution will cover the renaissance of transhuman revolution humanity’s first foray into cybernetics. The story is what is important and the teaser trailer gives away practically nothing.
Two words: CANNOT WAIT! However, knowing what a debacle the fan-filled lust for Invisible War was, it would be best if I do not have any hopes at all for this game. I merely hope it releases soon.
