For anyone who is interested, my review of Gray Matter is linked below:
Gray Matter Review - Alternative Magazine Online
It's strange, but although a lot of people have noted faults with Gray Matter (faults I myself could agree with to some extent) none of them impacted my enjoyment enough to really matter. The puzzles, storyline, characters and soundtrack all combined to create one of the most emotional, involving adventures I have experienced in years. I certainly hope we see a sequel at some point in the future.
