Agreed, the Dishonored series was great as well.
Also the System Shock and BioShock series.
Agreed on the System Shock, and of course if we are talking about Looking Glass games you have to mention the Thief influence.
Bioshock has never been in the same category for me, because it is very focused on run and gun combat, for this reason I’ve never felt it worked as an “immersive sim”. The levels aren’t nearly as open plan either. It’s still great in its own right of course.
