It's been a week since it's out, so I think it's a good time to start getting people's impression of the game.
Here's my review/impression, starting to come out of the initial 20 hours, somewhat boring, part, without any spoilers:

Basically, for me, the first part is a bit too overdrawn, but it's starting to get super awesome.
Let me know what you think, and if you've played the game, how do you feel about the game yourself.
