hey i have one question for GTA VCS. Whenever i destroy another gangs' vehicle and trigger an attack, after the attack passed and i could buy the building, how come whenever i choose what business it is and i scroll over to "drugs", "smuggling", and "robbery", it says its unavailable?? How come?? Am i supposed to finish a mission or do something before i can make a "drug", "smuggling", or "robbery" business?? PLEASE HELP ME. THANKS
