I heard you get all new cars weapons etc well would they appear on gta iv or only when i play ballad of gay tony, and im talking about the add on not the game that does not need gta iv.
if i understand correctly, TBOGT is an add-on, but you'll still need the orginial GTA with niko bellic, either on a physical form like the CD or if you bought it on XBLM (the niko story) on a digital form it will also play
