Hello, I've been researching and falling this game since E3 this year. I have played the game here at the PAX Seattle gaming convention two week ago. The game is mind blowing realistic. It is very highly graphically done. It uses a real time water/ocean simulator. It has a real time living environment. Which means live actual random events happen all the time. From other ships coming into view, to wild animals appearing, to weather storms moving in. At PAX, it was easily the most stunning Next Gen game shown. The main story line is about 20 to 25 hours long. But the games side missions and adventures is well over another 80 hours long. There is much to do and it is all very exciting with it random unknowns of what's around the bend. The game has actives such has harpooning big wild creatures in the ocean such has Great White sharks, etc. There are many many upgrades for your ship and you character Edward. The games online multiplayer is rebuilt to Next Gen specs in graphics and visuals. It also now has weather cycles just like the the single player game. This game is a easy day one for me.
