Maybe it was just too far removed from the games I'm used to, but I just didn't find it very fun.
I thought the shooting was pretty lame, similar to the last Tomb Raider games. It works, but it's not easy to get an accurate shot and not all that exciting or fun.
The characters were kind of interesting and the voice acting was quite good. But, I just had a hard time getting into the story. Maybe that's because I didn't know the back story.
Visually, the game is very well done. The open atmosphere is cool and the detail is very nicely done. All in all, though, I just thought the game was very slow to get started and the story fell a little flat for me. Maybe I'm just used to more action, but that's me.
