Are there any submarine based RPGs?

Reading this post, got me thinking wish we had a "Nadia - The secret of blue water" RPG. That would be fantastic: steampunk submarine adventures with a touch of Jules Verne at the end of the 19th century.

I've dabbled using Terra Incognita to create a campaign inspired by the Nadia series.

Probably not quite whatyou had in mind…

No, but the concept of "wet navy sub re-tasked as starship" (accidentally or otherwise) recurs regularly in scifi. The wretched John Ringo's Vorpal Blade features an example, there was another mil-scfi series from around the same time that featured a refitted navy sub being used as a space warship (a bit like Yamato in Starblazers, really) because it could somehow stand conditions close to the solar corona better than actual spacecraft (???), and I can dimly recall at least one from a pulp magazine in the 1940, There are doubtless many others.

A whole RPG might be a stretch, but yeah The Bonin Horse for Cyberpunk 2020 as someone mentioned and then of course Sisters of Sorrow for Trail of Cthulhu.

My friend at university ran a Nadia related campaign using Castle Falkenstein rules that worked really well.

There is an OSR B/Xish style Submarine "dungeon crawl" game in development called Sunk Cost on Itch.
