I played 20 hours of it but I haven't enjoyed it that badly. Sure there are some fum parts but there are also A LOT of boring parts, especially all of those moments that have no relation to the game's story.
I was so far from being entertained that I dropped it in 20 hours and I will return to play some other time. My cousin who had already finished the game said the game get's a lot better at the point I was (The 2nd Island) but I was not paying to see it. Maybe at the middle of the year or so I'll keep going from where I left.
But if there is one thing I really loved in this game was the soundtrack, I simply loved it. There were times when I wasn't much in the mood to play it but I kept playing just so I could listen to it.
Don't get me wrong, I think it is a good game, I just get pissed off when you're playing something that takes forever for the story to move onwards.
Jam it back in, in the dark.
