I just got an e-mail saying that my GTAV has arrived at my house (I'm in New Zealand, so it's Tuesday morning).
So in anticipation of happily wasting hundreds of hours of my life I'm going to pre-emptively ask this question.
Every other GTA game has locked out sections of the game map until you advance to a certain part of the story. There are also generally tutorial style missions that need to be completed.
I just want to be able to get out and explore all of San Andreas (preferably by dirt bike and mountain bike) so can someone who's faster than me let me know how much gameplay is required to gain access to the entire game map?
