A 5 euros, go

Warning, the game deserves adverse criticism. I did thoroughly on a PC gamer there 2 years, with 4GB of RAM, which have proved very inadequate: regular reboot necessary given the infamous amount of memory consumed by the game
Several bugs come spoil the adventure, including problems of the guards who are stuck in one place instead of making their scripted path.
No way to move other than on foot if it facilitates the roleplay, when trying to make the game 100% after a while it's mostly very making use.

Now I am writing this review while I see the game 5 euros on Amazon: that price, it's a great buy
As much as it leaves it probably deserved not a new purchase, so the game experience, past mistakes and various problems, is very nice.
For little that clings to the atmosphere will be unforgettable chapters (including a stressful chapter in an asylum)

Game time is more than acceptable if we try to make the trophies, and trying several styles of play: namely, the fact of never knock person (game style "ghost"), which requires a much more reflexion. Allow 5-10 hours to play "normally" but 10 times that amount if you are looking for and replay all the treasures

Conclusion: it is certainly not a perfect game, but it is a have if you like the style infiltration
