This is a little disappointing to hear (from the IGN Thief review):
The multiple approaches Deus Ex, Dishonored, and Hitman Absolution always seemed to give me were what made them among my favorite games of the past couple of years. I hate it when I'm forced to figure out the one and only possible way to complete a mission without being detected and getting into an unbalanced combat situation (although those games provided plenty of firepower as well if you upgraded yourself for it).
In certain scenarios, mostly the side missions, things open up and give you room to decide how you want to get in and out of a building, with options to like going in through the vents, the basement, the roof, or just barging in the front door. You’re rated on each mission by what approach you took and how often you were spotted, so there’s lots of incentive to go back and try different approaches. It’s just a pity that developer Eidos Montreal didn’t realize that this is what Thief should be all of the time, not just intermittently.
