I AM SUPER GLAD to read that you have clocked in 45 hours and you have not yet finish the game. I'm on 20 hours now and still discovering. Finally pick up the big bag. I really think that salvaging items as stole the show for me. I still love to see the animals, but I love finding stuff.
As far as the sharks goes, they annoy more than scare me. I won't spoil anything for you jarod, but you will see much more action in the hours to come.
I also enjoy the different characters in the game. Plus, the aquarium is much more interesting this time around. Plus, the private coral reef is pretty cool.
