Hi,
I also just followed instructions and learned what I could in the beginning museum part and talked to the people on the dock and the guy with the equipment. I was on the Titanic wreck in 1 (long) night. Now, I can get into the wreck in just a few minutes to poke around. There are clues everywhere for finding the wrecks in the museum. The boilers, the valise, the megaphone - so much to see in the debris field and of course the wreck is pretty cool. Being able to save photographs from your ROV/sub is also very neat. I really enjoyed it! Sure, it is a bit corny - but it's also a bit cool. Also, under the stern/poop deck and the props - great place to look around, as is the bridge and going down the staircase. And the nice doors, rooms and other details near the break on either section. I still find stuff I have not seen before. It can even feel claustrophobic - I play with the lights out and the stereo up.
Best,
Eric
