I'm in the same boat as you regarding job and time. Also, I'm 42. :) I have done many small projects with Unity, but all mostly like tech demos. I've done a vr game for the global game jam the past 2 years, and I did this jam last year, but we were too ambitious and didn't get to submit.
I'm interested in someone else leading and I can just code or possibly make assets if voxel art is needed. I also have an artist friend who can work in blender or voxel art as well.
