I have done nothing but story mode so far, completed about 14 missions and I'm 16% done overall. Finally you can choose between the 3 guys Trevor, Michael and Franklin, all have a bit of money so you can buy weapons and what not.
Oh and purchasing property is now possible. I only own 1 bit of property so far and that's a small airfield with a couple plains in the hangers. Enjoy
