i would like to do the big surf island campaing but i don't know if it's possible with the vanity pack
does a save exist without all unlock ?
Due to limitations in porting the street data, events, Road Rules, and traffic aren't in Vanity Pack. The cars are unlocked from the start because there is no way of unlocking them otherwise.
If you want to play through the BSI campaign on PC, you'll have to wait for Xenia or RPCS3 to develop further.
