I loved the original Deus Ex and think Cyberpunk does a good job of carrying the torch. While it is clear both games have different priorities in terms of writing and activities but they both have a similar heart. I think Cyberpunk puts a lot more points into atmosphere and worldbuilding than DX ever did, personally.

And nonlethal options are presented to you as part of the tutorial. I agree that lethal/nonlethal doesn't seem to make much of a difference, but if you do stealth and melee combat from the start you have a path for nonlethal that will get you all the way through the first major mission. From there it's relatively easy to acquire PAX mods that turn any gun nonlethal.
