Well at least they are consistent with the storyline laid out by the first game (timeline wise).

who fucking cares about the health bar??
I liked the atmosphere and depth of the world and the characters that they obviously put massive amounts of work into.
Also the many different options available to you in each scenario and the huge scope for exploring, snooping around, talking to people and discovering more about the compelling world they've created. Thats why I felt it to be a worthy sucessor to deus ex 1, as those were in my opinoin the elements that made it such a great game.
but, if the health bar is a big turn off for you then by all means dont play it, just go stick your head in a bucket of donkey giblets instead.

Deus Ex.

I also hate this masterfully crafted fictional universe because the gameplay implements a standard modern feature! Next thing you know, you'll tell me there's a mini-map and that I don't need my graph paper!

First we had a Cena Mark, then a Cena Mark of anime, now a Cena Mark of video game features?

I read that the replenishing health bar is just on the easy and "normal" difficulties. They said a while back that veterens will want to play the harder difficulties.

Yeah your PS3 won't let you play otherwise.
