Bump this 3 years old topic.
(original idea on p1 of this thread)
Surely this idea coud now be possible with the scenario options of the new Oolite?
The way I can see this implemented is. Travel to Galaxy 3 planet Aqualina (need Aquatics oxp) and make planetfall. Then you would be transported to a surface port where the Ocean map is presented. And then you could travel to places on the map. Systems are now regions of interest and marked with a number which indicates the depth. Deeper = more dangerous but could give greater rewards.
The color of space could be used to indicate the depth around an underwater station. Colors could range from very light blue to pitch black.
Space dust could be made bubbles. etc.
Other way to implement is via the interfaces screen where a game setup as a sort of combat simulator could transport you to an underwater scenario.
Anyway I thought about this suggestion again today and it would be really cool to see if someone can come up with something like this. Basically a total conversion of Oolite to underwater. Name could be Oolite Escape to Aqualina or something like that.
