Again, in what significant way is Thief lacking in that department in comparison to say, System Shock 2 or Deus Ex? Those environments are mostly static too, besides the usual doors you can open, junk you can throw, crates you can stack(this option isn't in System Shock 2 by the way) and the few objects with special functionality you can use, like the medical bays or the repair bots in System Shock 2. I know you're going to respond with something like "You can hack computers, log in onto them and multitool devices/lockpick doors" but all those fall under the "few objects with special functionality" category. And once again, I wouldn't mind more sensible interactivity in Thief, I just don't find it as lacking as you do.
