Seems to be hinting at missions and they look epic. Parachuting on to a train (to rob it hopefully), chasing a jet with it's engine on fire!
PS: Any plans to make the /V link the main one. I love that site's design.
Hm...Another construction shown. Is anyone getting the idea the world changes as you play? Shops shut down/open. Houses get sold/bought. Buildings demolish/reconstruct? etc.
They showed some of those in 1st trailer too.
Because I really think that is level of detail Rockstar might target and I think it'll be really cool. Especially if you can go in some freakin' building this time around (and they don't all have the same interior).
