Hi! I'm Co-GM so I'll try to help you out!

Your hunch was correct and that a lack of backstory and personality did leave your Characters a bit bare. Not a problem, though. There are plenty of places to try and expand. Like for example, in Megan's story it technically wouldn't be possible for her to just leave the NCR after completing boot camp. That's not how a military like the NCR works. However if Megan decided to skip her duty after training, it would brand her a deserter and a criminal, her parents end up dragged through the dirt as an extension and who knows, maybe Megan's parents are executed for their daughter's crimes. Details like that adds a lot of spice to a character which later makes them more fun to interact with. So think about some things like that to add to Megan. Ask the who, what, where, and why questions at every major point in their lives. Who are they with, what are they doing, where at? Why? So on and so forth.

With Darius, same thing. Why does he have nothing? Was he robbed? Decided he wanted a simpler life? Up to you, really. I'm sure you can think of some extra bits for you charas.

Oh and you mistakenly added an extra Tagged skill to both characters, which is a no-no unless under specific circumstances listed in the rules (ie taking the Tag! perk or taking a weakness skill)

I hope this helps!
