Not sure if this has been suggested before but since just recently checking out (and loving) this project, I thought it would be really cool if you could either create or edit a Soldier's background. I love the random element and I know that's what your team is going for, but I'm one of those X-Com players that love naming their Soldier's after people they know and getting invested as they take a shot or do something heroic.
So, I think the Soldier backgrounds are a brilliant idea and I love it, I'm just wondering if it would possible to let you "fill in the blanks" so to speak on Soldiers. Especially choosing their nationality would be really cool. The extra/step idea on this would be to "recruit" soldiers and let you pick and choose how you wanted them, superficially of course, not so much stats.
