I want to make this abundantly clear because apparently I haven't already:
I WILL NOT PUNISH SEX. I WILL NOT PUNISH FOR INNOCENT ROOKIE MISTAKES. I WILL PUNISH STUPID ACTIONS TAKEN WITHOUT THINKING.
If you do something so blatantly stupid that I'm left staring at the screen dumbfounded, I will punish you for it. This can include shooting someone just for looking at you funny in broad daylight on a busy street. This can include trying to rob a strip club. This can include walking down the street in illegal armor in full view without even trying to conceal it. Yes, sometimes we forget that our armor is illegal, and I understand that. But if I remind you, and you still do it, I'm not holding back.
Now, on to Mr. Injun Joe... yeah, that's not flying. Reason is, if you're in the Mexico region (Also referred to by Atzland), there are native tribes there too. If you need a reference, check here
for various tribes you can use as a background. If your heritage is Mexican and Native American, you might pick up the name Jose Xiichipari (White Horse in Matlatzinca) from the village of San Juan Atzingo, not far from Cuernavaca, which is a decently sized town south of Tenochtitlan (Mexico City). If you need a street name, try Caballo, which is Spanish for Horse. It ties together your heritage and the horse is powerful yet graceful and very fast. Just a suggestion.
If you want to be part of a street gang, fine, but if you're new on the ShadowRun scene, you would pop up on someone's radar if you had an Aztechnology bounty on your head. If you did get that bounty, what are the details? Why did you flee to Seattle instead of, say, Amazonia? Or even to Europe? What makes Seattle so appealing to you? Is it distance? Because there's a relative there? Give me details so that I can make use of your backstory. Remember, the more details I have on you, the more I can tweak missions to be more interesting to you and your character instead of just a job. Maybe the job targeting Aztechnology could give you the chance to erase your bounty. Maybe a job with Ares includes an offer to pay off your bounty. Maybe someone comes gunning for you after recognizing you from a wanted poster. The more you give me now, the more I can give you later.
