10 yrs later and we are still saying that.
Because it's true..
I'm not quite sure whether to say that it's unfortunate that it's true that no-game since has managed the blend that well or better.. Or just think that Dues Ex was just that damn good.
IW is the second best game done in that style because Deus Ex is a 2 game genre. Other games have done parts of Deus Ex better then Deus Ex, but none of combined it all and in all honesty, none have tried.
I look forward to AP, but it's not going to be Deus Ex. So far the only thing on the horizon that sounds like Deus Ex, is Deus Ex 3.
