But how would you rate Deus Ex so far?
It's a great game. It's too early for me to say if it'll end up in the realm of awesome, that will depend on how the story develops. But the mechanics are great. I love the conversation system. With the right augmentations, you get a lot of advantages in conversations, by letting you read body language and such. But it's not as simple as that unlocking new dialogue options or telling you which is the right ones. You first have to see which type of person you're talking to, and select according to that. Or you get a summary of their personality and have to influence them in real time.
Hacking is great, too. It's difficult, but not unreasonably so. And again the hacking minigame is more elaborate than what you see in most games ( like Fallout 3, Mass Effect 2 ). While hacking, you can also decide if you just want to hack the door and get it open, or make it slightly more difficult by capturing optional "nodes" for a bonus ( experience, cash, viruses ).
Stealth is difficult, and not as streamlined as in Splinter Cell: Conviction, but it's not bad.
Shooting I can't really comment on, as I haven't shot anyone outside the tutorial.
If I were to compare it to another game. .. I'd actually say it has a lot in common with Vampire: the Masquerade - Bloodlines. Which is one of my favorite games ever, so go figure.
