A steay thought I've been thinking more on: marriage-powered mech. Or commitment-powered mech, anyway? Those stories have been around before.
@ryusei You have a point! I was equating love and commitment when I was thinking of that. I think it would be interesting if I specified that, then, and there were pilot teams that were expected to take sabbaticals from each other because they needed breaks from each other for work and personal reasons.
@swordjaw That does sound really interesting. Go for it!
