The AADA is the AAA analog in the Car Wars universe, which the Steve Jackson game system Car Wars exists in.
It's like the American Automobile Association, helping you with car stuff, like maps and locations of good motels and gas stations. Except they also provide essential services for Auto-Vigilantes, like discounts on ammo and car-mounted flame throwers.
If you plan on going out into the badlands with your machine-gun equipped, plas-steel armored, electric-motored vehicle to kick some evil-Mad-Maxish-badguy's butts, make sure your Gold Cross insurance and your AADA membership dues are paid in full. |
