Do you like fluid physics?
Do you enjoy sandbox games where you can just mess around with the systems?
Do yourself a favor and load up the terrain tool. Select a new one. Use the sea-level tool and raise the sea level to your desired depth (the deeper it is, the bigger the waves. Now at this point, BE SURE to set the games "speed" to max otherwise the water moves sort of slow.
This game uses what I think is an incredible fluid displacement and movement system. Take the land raising / lowering tool, set it to a large brush, and set the strength to max. When you raise and or lower the land, the fluids will realistically move to compensate. You can do some CRAZY things with the water, especially when you then zoom way down to water level. I've managed to create some pretty interesting Tsunamis, tidal waves, etc.
Now, another interesting thing you can do is to create your own terrain, a place you would actually want to publish or play on. Put a coastline on it and put the sea level about where you would normally want it in an real game. Then do the exact same thing I mention above. It will flood your land. However, the water will eventually retreat back to the ocean leaving behind some interesting, natural looking lakes, etc.
Has anyone else messed with this? I think it is insanely fun and interesting.
