When the time comes for water to be added into the game, I am curious as to how it will be implemented for existing worlds.
I am presuming that firstly there will be no water added close to parts of the world we have already been building on, and secondly that once it has been added we will need to drink water for the survival aspect of the game. If this is the case, then obviously we will need to be travelling a long way regularly in order to survive.
Therefore, I have the following suggestions...
1. Make it to be possible for us to create a channel which the water could flow into, therefore bringing it to our built up areas.
2. Failing the water being able to flow by itself, some sort of pumping mechanism (and possibly pipes) would need to be implemented to bring distant water closer.
3. If there will also be underground bodies of water, allow these to be created under areas we have already worked on, as long as we have not already dug too close to them.
4. If there is underground water and we dig wells, there will also be a need for some mechanism for getting water to the surface.
A related suggestion - At some point can some of the items like sinks work in some way. (ie, could you connect a water source to a sink (via pipes / pumping / some other means) and obtain drinking water from it?)
