According to a recent post on Reddit, game company Take-Two Interactive has already registered GTA Vice City Online.
The parent company of Rockstar Games has seemingly registered a domain called GTA Vice City Online, which could mean a possibility of a sequel in the works. The Reddit user who posted about the new domain also revealed that “gtavi.com” just got updated alongside that other domain. This is curious since the original game did not have any capabilities for online features.
Some are saying that this is just to acquire different types of websites related to their projects and titles. Others are saying that the next game might be set in Vice City. Some even go to some weird lengths saying that VI is just somewhat signifying Vice City.
Again, this is just a rumor and not officially confirmed by either Take-Two Interactive or Rockstar Games. Take this with a grain of salt.
