Is there an online game like GTA that is worldwide and alows you do to anything and be anything?

Run a mortuary for the mob, be a mob boss, be a CEO of a large corporation and buy up other corporations. Steal from your neighbor, kill your neighbor, merry your neighbor or go to college and study. Like the real world goes cyber reality type game. Raise a family all kinds of fun stuff like that ... have a dog, a job or 3, be a secret agent with a family ... :-p maybe even travel through time and change the future. Oooo this game is getting good. Like a time shifting, universe, where anything is possible and you can do anything ... run a sandwich shop, build bombs for a living, own a dog kennel. :-p haha go on vacation and cook spaghetti for your girlfriend but don't tell the wife. hahaha :) fight Darth Vader today and live through juric park tomorrow :).Un berryy the stargate and travel around the universe building tombs. Ahhhhhh it's getting crazy now!
