Lighting does matter in the original game, it has the same stealth system as the Thief series, but no one said the AI was fantastic.
So essentially lighting doesn't actually matter in the original game since the AI is so poorly done that it doesn't make much difference.
Deus Ex isn't perfect, and I'd love to be spotted by AI while leaning. (So they should have taken the chance and improved that in HR instead of simply removing it completely) Even so, it's much more challenging when you have a limited view from leaning, compared to the camera moving up and over crates, and around corners. You can even see over higher cover than your behind since the camera raises so much.
So don't use it then.
K? So every mediocre run and gun shooter uses it, so that means it has to be perfect for a highly tactical RPG with an existing inventory and consumables.
Stop being obtuse, even roleplaying games have had regenerating health. And since when has Deus Ex been a highly tactical RPG?!?
Don't bother making counter points, because I don't care to debate this. It's my personal opinion that they have dumbed down the game to appeal to a mass audience. It appears to be a very simple, easy game, with very annoying interface and HUD features. I don't care if you think it is isn't.
Right. You are just looking for things to hate about the new game and all you have done is exaggerate or invent things about both of them.
