Some random thoughts after finishing the first mission:
Tranq rife is OP. Seriously.
Deus Ex, like so many games with RPG elements, is a lot harder at the beginning than at the end. I've always found that kind of funny.
I'm going heavy into hacking, which means I'm already dreading the first boss.
What weapon is everyone using as their main? I'm going Tranq and will probably upgrade a 10mm through the roof. Not sure if I'll bother with anything else. I loved the sniper rifle last time I played but it's too big to carry around.
