Neat Online stuff those who bought the CE:
The Collector's Edition of GTA V has additional in-game exclusives. In Grand Theft Auto Online, the game's recently revealed multiplayer component, three characters from previous Grand Theft Auto games will be usable as parents in the hereditary creation system (which determines what playable characters look like): GTA IV protagonist Niko Bellic, GTA III protagonist Claude, and Misty, a prostitute encountered in GTA III. [5] The CE also includes an exclusive garage for storing vehicles, as well as the CarbonRS bike and Hotknife hotrod for use in single-player, and the Khamelion electric car in GTA Online.
If you didn't know about the Online character creation part: You basically pick your parents and grandparents and that determines how your character looks, you don't make it yourself. It also determines your background and some other things.
