If you love Deus Ex, I think the Dishonored games carried the flag for this kind of game too. Harvey Smith, lead designer on Deus Ex, was heavily involved in making them and while the setting is completely different (magic, steampunk-ish), the “feel” of the games owes a huge amount to Deus Ex.

Dishonored 2’s fictional city of “Karnaca” gave me similar joy to explore and unpack as when I first encountered Hong Kong in Deus Ex.
