Are there any submarine based RPGs?

[Umbran]

I suddenly want a seaQuest DSV RPG!

What does it need to make it 'submarine based'? Special rules for decompression? I figure any modern-set RPG can be set in a submarine? That's just the adventure plot, surely? Like D&D might be in a castle or a desert.

Isn't that a tad dismissive?

I would expect a submarine (or at least a modern nautical) game to have specialized nautical vehicle rules, nautical ship combat, rules about depth (& thermoclines, and sonar detection for modern settings) how to run combats underwater, including the differences from how you expect normal weapons (or spells) and explosives to work...

It may not need to be a full standalone game, but a serious treatment would probably be a notable supplement for most systems.

I've run adventures that take place in submarines (both functioning and wrecks), but I don't know of any RPG specifically geared to ongoing submarine operations.

I'll ditto the recommendation for Blue Planet, albeit I've only ever done a quick read/browse of it and that was years ago. IIRC it's d100 based and I seem to recall it being a more than decent implementation of such rules. The creator of it (Jeffrey Barber) taught oceanography and that's reflected in the content. The best thing about it that I got even from a browse, is that although it's packed with technical content, it's presented in a way that's easy to read and grok.

And yeah, the tech in it that had a cyberpunk vibe was very cool.

Another vote for Blue Planet. The production quality is/was spectacular, and the setting is extremely good.

Its only weakness that I recall was a very thin metaplot/enemy faction.

Wasn't there a new edition Blue Planet Recontact coming out?

Crush Depth Apparition is great submarine adventure:

Crush Depth Apparition by amandalee

eerie survival horror on a haunted submarine, a stand alone ttrpg now funding for Zine Month

Amanda's other sea adventures, You Got a Job on the Garbage Barge and Vampire Cruise are also fun.

Right? I would also accept a more retro game inspired by Voyage To the Bottom of the Sea. Irwin Allen still retains a certain schlocky charm.

Wasn't there a new edition Blue Planet Recontact coming out?

Yep. Third edition, apparently working with Gallant Knight Games of Tiny d6 fame (although it isn't using that engine AFAIK).

Polaris looks like a really fun and creative underwater RPG:

I think Blue Planet is the way to go, I've had a quick read of looks pretty interesting. They're just so underrated in my opinion
