"about the camera " I love it.
"weather - i hope so, but " OK. Maybe scalable in options for those with high end vid and cpus? Also, maybe increased cloud, background sky, sounds, and crew weather report "Storm a brewin, capn".
"global navigation - this is campaign level"
I vote for waypoint planning on chart with "return to course" order when diverted due to action. Also I vote for, if possible, navigator take a sighting and report position with % accuracy circle around actual. Maybe navigator quality/experience determines size of error.
"troop transport - this is certainly possible"
Excellent. Maybe we can learn how to contribute scenario/campaign design to help.
"land actions - capturing ports, cut-out missions, and the like"
Perfect! A naval game should not include land fighting. Get them there and let them do it. I agree.
command interface -Looking forward to this
bathymetry - yes. Unbelieveable. Fantastic ideas. I am just now reading the log of Christopher Columbus (a book) and he had lots of issues with narrow channels, sandbanks, currents vs wind, and so on.
Great stuff.
