By itself, this is not a bad game at all. You have to change some options to really make it a somewhat Thief game and that's where Eidos failed at with this on making it too easy out of the box, but it's not necessarily bad at all. I still put in over a 100 hrs into it on my Steam account. My biggest complaint with this game is that it was catered to consoles and because of that, it was to easy out of the box with focus enabled (blue outline on anything interactive) and people could fly through it. When it was originally launched, it got a ton of negative press because people could complete it in less then 10 hrs and for the price of 60$, it wasn't worth it and if there was no way to turn that off, I'd have to agree with it but you can and you should. Eidos got this wrong. If you go into options and disable the focus and some other options, it becomes more of an actual Thief game. There are still the "loading" issues which is still irritating but this wasn't as bad as a lot of people make it out to be if you disable all the things that make it easy. The ending still felt off and some other parts of the story but overall, if you disable the things that basically hand hold you and tell you what to click, it's a much more enjoyable experience. Get it while it's on sale and judge for yourself but you'll get a good couple of hours out of it for a couple of bucks and worth it in my opinion.
I realize that it's a different platform but this game is worth getting on any platform. With the new multiplayer option available, it's even more fun. After this much time into it, I really haven't had the bugs that some of have said but like others have said, it's a lot like BG3 but seems to be more balanced. Not as graphically polished but it's the game play that's the focus, not cut scene graphics. Both games are a win, don't get me wrong, it's awesome having these options again. Seem to be such a dry spell in the turn based, RPG genre for a while.
