Rockstar Games has announced that those who wish to fast track their progress in GTA Online will have the option to purchase GTA$ via the in-game store. Rockstar says that the game and its economy were designed and balanced for those who will never buy extra GTA$.
Rockstar says that online players will earn in-game money much faster than in GTA V and that there will not be a shortage of cash to go around. The developer also warned of growing pains when the game launches. There may be bugs, performance decreases, and other issues as the servers are stress tested for the first time. Rockstar says that they will address these issues as they arise.
