Orkhepaj: I didnt have those bugs, maybe got lucky , without it game is enjoyable at least for me. It has stealth arrows and loot what else is needed.
Sorry but "Thief" 4 is an awful game. As far as cheap & nasty 'obvious cash-in' sequels go, I'd place it right up there with Dragon Age 2 and Deus Ex: The Fall. It was saturated in development hell and almost got cancelled at one point. Some of the few original Thief developers they had walked out when it became apparent the "new guys" hadn't played the originals at all and were flailing around clueless as to what they were supposed to be making beyond
"I like Batman & Dishonored, so both with more loot right?..." The entire point of the Thief games was that you played as a regular guy who wasn't "special" in any way, not as some superhero with Batman-vision, and Corvo-style swooping / time-dilation magical powers. Call of Duty style
"Get 4 headshots" side-objectives from the 1st mission set the stupification tone from the start. Throw in checkpoints of no return (that killed open-ended exploration / backtracking), pay to win "Booster Packs", the light gem already got dumbed down from 11 to 3 states yet even that needed further dumbing down for the "casual audience" by flashing the whole screen white in the most intelligence insulting way possible, button mashing QTE's to open every window,
level sizes that were drastically shrunken vs the originals, and finally replacing the distinctive voice of Stephen Russell with "Painfully Generic Voice Actor #384" concluded with "Confused Batman-Dishonored Wannabe Ripoff : Thief Texture Pack Edition" that was received so poorly it was the primary reason for Square Enix cancelling any plans for Thief 5 and permanently shelving the whole franchise...
