I think it's kind of a unique idea with a lot of potential...however, I have one BIIIIIIG nitpick.
At least from the standpoint of the LPI, as I'm a Deputy Chief there, I do believe I can say this:
Don't expect us to hunt you down because you're kids in spaceships, we don't fly around with a list of missing/runaway kids from all over Sirius, so how are we supposed to know who any of you people are unless you tell us? And even if you do, it's not our job really. I welcome the opportunity to meet you guys in space for what's hopefully some interesting and unique RP...
Buuut I guess the point I'm trying to make is this:
If you see yourselves as hostile to the -Police- factions of the Houses, it's simply because you want to be hostile to them.
Aaaand, you certainly shouldn't see yourselves as hostile to the Military factions of -any- House because seriously? They're the military/Navy/Armed Forces, they simply don't care about runaway kids unless those kids are blowing stuff up.
Nooooot trying to sound harsh but really, barring your ID choice, there's no reason for you to be Hostile toward the Military or Law Enforcement in the Houses.
Just something to maybe think about.
Other than that, it seems like a kinda cool idea and I wish you guys luck with it.
And as said before, I certainly welcome the chance to meet any of the affiliated characters in game on any of my characters.
