I need to know whether people will be interested in it. I will be making M-Bot from Brandon Sanderson's Skyward. If you don't know what that is, go read the book, it's PG and it's great.
However, there is another thing I want to build, and it fits into the story I'm making. It is a lander/escape pod that is intended to be docked to a main mothership. Once in the SOI of a terrestrial planet, it can undock and land. Once landed, it will be able to take off again, redock (assuming ship is in a low orbit) and refuel for ferrying. It will have 10-15 crew capacity, and canonically will be piloted by an AI, which the player will take the place of.
Both of these builds will have a completed interior, and be cannon (or at least as I can get). If I do decide to build one of these, I will finish sometime in two-three months (assuming no major setbacks or life catastrophes). So final question, which one should I do?
