Whoa ho ho!
I like the look of that "3 ways to play" video. Reminds me a lot of the original Deus Ex.
Although unless you were really badass in the original Deus Ex, being aggressive often got you killed (unless you sneaked around and messed with the security systems and picked off stragglers first :P).
Also, notice how many times he got shot at the start of the aggressive part.
Finished this game some time last week.
Was great fun, but I don't think i'll play through it again since the game doesn't appear to change much depending on the choices you make (just occasional bonuses like making less enemies appear, or giving you better weapons earlier).
I picked the Sarif ending, because that's what appealed to me :P
