I originally left this comment on TCB's video but the comments are disabled (oops didnt know, makes sense though).
I couldnt play when I first got the game and I had prepurchased. It actually took me about 3 hours to get the game working because everytime I changed an option to optimize my game I HAD TO RESTART IT. That being said I love the game. It reminds me of the fun I used to have playing MYST and Ultima Online.
