If you've been following me for a long time, you know that before Airships, I was working on another project called Space Exploration: Serpens Sector. It was a space RPG that started out as a clone of the original Strange Adventures in Infinite Space, and ended up being something like Sunless Sea in space with less florid writing and a bigger focus on crew management.
As mentioned before, I do not have a release date or a regular update schedule, hence the recent silence. And on the topic of refusal, here is a list that the game is not, and will never be. In any kind of project, you should not only list the goals, but also list the things you specifically don't want to achieve. This lets you define the shape of your project, and to avoid mission creep.
