What is everyone planning, if I may ask? 
Tell me your ideas, both mechanical and narrative, a little bit of history if your project has any.
I am just curious. 

I have an idea of making the mechanic based off of the Ocean Exploration Trust Nautilus livestreams. How am I going to do that? Not sure yet!

I'm doing one about underwater cave exploration with elements of horror. Nothing too fancy, a simple cave mapping/generation system, a gear upgrade mechanic and some rudimentary combat.

I am doing something a bit more on the surreal side, using Water and Sailing as a metaphor for traversing a dangerous realm in your dreams.
