Buy it, get it, play it, etc.
Very good game, one of the best of that year in my opinion. Great story, memorable moments, nice use of the Mental Echo ability as both a unique gameplay mechanic as well as a very interesting and interactive way to advance the story and making you feel like you've made a difference. The atmosphere is also very well done.
The game is pretty poorly optimized and runs at a low frame rate on many computers (I finished it with about 15-20fps on average on my old computer, but still enjoyed the heck out of it). The combat's kind of clunky too, but it's not bad enough that it can't be overlooked.
