About the economy, Dan Houser says: "You will be able to spend money to buy interesting and fun things like expensive toys. We are still working on the economy but it will be a strong element in the game and players will be eager to make money to spend money. Something along the lines of "I went through all of this to make all this money and now I'm going to spend it on this crazy item."
I think people are really overlooking that interior spaces were included in the stuff about the map size. I expect the map to be plenty big, but not the size people seem to expect. But it'll have a ton of playable buildings like a Bethesda game.
Can't believe how much I'm waiting for this game. I've sold half of my games away during last month as I don't have time to play anymore (haven't even played NBA 2k13 yet, had it like month already), but still GTA V is a must buy when it's released. Seems like the map is huge, and it will be interesting how we can use those three playable characters. + interested on seeing what little activities we can do during and away from the story line.
