Gameplay is fun for about the first 60 minutes.. :-/
The graphics are ok...for the vessels...the landscape at first glance looks nice, but within the first hour of playing the game, it becomes redundant and boring, that actually goes for the whole game.
You can select different types of vessels, from small speedboats to huge container ships, the parts of the physics that are actually present is well done, the boat react properly to waves and so forth.
Its possible to set up weather conditions and choosing a location where you want to travel around, you can choose the size of the waves, how much wind, sunshine, rain etc.
Nevertheless you cannot create any extreme (read: exciting) conditions, like supersized waves thatll make your speedboat go airbone or let you get the experience of driving a tanker and se the waves flushing across the decks.
There are several viewmodes/cams to choose from and there is even a "free roam" cam, so you can walk around on your vessel, but yet its rather buggy and you can easily fall over the side and into the water and from that position everything looks weird and messed up, kinda ruins the visual experience.
The gane in general lag dynamics big time, you can torture a vessel by driving it into land, structures or whatever, there will then be visible damage and even holes in the hull, but yet the vessel wont tend to sink, it just gets slower according to the lvl of dmg (0-100%).
Conclusion is, that the game is fun until u have tried the different types of vessels and the different types of weather, ithen the game starts to repeat itself in every way.
Making the game better would take some work on the details, like implementing more physics so that you will actually be able to se damage done to other objects, making the vessels sinkable and add possibility to tune the weather "out of control".
