I've tried to make the game world as interesting as I can. GearHead features a number of different cities, and hundreds of different NPCs. Conversations are resolved with a menu system similar to that used in many other CRPGs. There are twelve different factions of which the PC can join seven. As a campaign progresses, the PC will make a number of friends and enemies who may show up at various times to either help or hinder his main quest.​
