Thanks for the kind words! Yeah, I do think once I got the ball rolling with how a multi-person telepathic submarine might work within the game systems, it really opened up a whole world of opportunity. My first expansion Invertia sort of ended up a dumping ground of a lot of dissolute ideas, but I think Abussos will be a lot more solidly directed along a theme.
I will certainly hit you up for some adventures when I get a bit more solid background laid down. Am currently trying to write a few for Invertia and struggling a little with the compression in scope. My current thoughts are that Abussos is going to be a lot more open in general, to allow for Vessel based exploration with finding things floating in the endless ocean being something akin to a space hulk like affair: mini dungeons where your crew is suddenly pressed into cramped, dark spaces trying to explore what you can before fleeing back to your ship.
