I'd love to give this game a glowing review because it was great for me, but it is apparent from reading the forums that many people have issues running this game. For this reason, I'll supply my specs, though I cannot certify that this will make the game run for you:
Win 7 64 bit
Radeon HD 7770
AMD quad core 2.94 ghz
On with the game,
It's an adventure game with a few twists.
First off, you can operate the game from two different perspectives: Third-person for the old school point and click feel, and first person, which I prefer.
Besides the collecting items, you will have the opportunity to examine crime scenes and fill out some diagrams that include the clues you've gathered. The game won't let you fail these. Though at first thought that might seem lazy, the game is pretty much packed with detail and it's hard to see the devs making branching paths given the amount of attention and longevity of the game. Along the same lines the game also won't let you leave certain areas without collecting all the items.
There are many texts to read in this game and I would say that it is important to read them, as most do divulge important information that is pertinent to your case.
The voice acting, aside from one character who is thankfully absent for most of the game, is top notch. You can tell that, even though there was a budget as far as recording goes, the devs spared no expense for finding actors who wanted to portrey their roles well.
The music is fitting and includes some great pieces from the Romantic era including one of my personal favs, Schubert's Trio in Eb.
While the puzzles can be hit or miss, they mostly hit. They make sense and you should feel like you understand what the game wants from you, though there is one puzzle that involves a map that is somewhat obtuse given to a problem with widescreen resolutions, but it is do-able without much fussing about.
Though the graphics aren't the best by today's standards they do the job. The environments are well done and I felt very immersed in the places the game put me in. Hookers, drunks and theives around every corner.
All of these things came together for a perfect storm of presentation. Nothing felt out of place and I was enthralled with this title from beginning to end.
If you're looking for an adventure title that'll suck you in you should definitely give this title a go, though you should do your research to figure out if it'll run for you.
