Hey everyone, I’m a long time fan on the Civ series and I’ve been lurking on these forums for a little while. Thought it was about time I got involved, thanks for making this such a welcoming place! So I came across a video on deep sea mining earlier today, and I thought it would be such a good theme for Civ. Just thought I'd share. ( Video here for those who want to watch - https://www.youtube.com/watch?v=_vgRQAtPSMU). In short, hydrothermal vents on the ocean floor are home to a vast number of undiscovered species. They also spit out precious metals like copper, gold and zinc which can be used for modern electronics. So there's a battle brewing between those who want to protect the unique ecosystems and those who want to mine the materials. I've always found exploration to be my favourite part of the game, so it would be pretty cool to be able to search the ocean floor in the late game for hydrothermal vents. If you find one you could then have the option to study and protect them for science and culture, or mine them for precious metals (and maybe an empire wide production bonus). With Geothermal fissures and volcanoes already in the game, it seemed like a natural fit. While they’ll probably never exist in game, I thought it might be fun to discuss. Anything else you would add on theme of exploring the deep ocean? Thanks for reading!
