I hope they add more options to the multiplayer free roam.
I've probably spent several weeks of my life playing GTA IV free roam but always got pissed off with noobs in the helicopters, they were great fun if everyone is up for a dog fight, but when you're having a good old street battle on foot and some idiot just races for the nearest heli then proceeds to kill everyone as soon as they re-spawn that really grinds my gears.
If the GTA V map is going to be so much bigger than IV's, then they need to limit the availability or range of helicopters/fighter planes, otherwise people will end up being stranded in the middle of the desert with some fool blowing them up as soon as they spawn. Being able to turn them on or off in the lobby would be better.
Also instead of releasing DLC like TBOGT and TLATD, they should release extra mission packs, so for another £10 you could buy 30 or so new missions, its a quick cheap way of keeping the game interesting, you could even have player designed missions through the social club.
This could also work with weapons/vehicles - cheap or even free downloadable packs with a bunch of new stuff.(the new guns added in TBOGT were great) .
It would be a big move if the entire map was unlocked form the start, it always seems a bit silly to me that most of the map is unavailable for the first part of the game? especially as this is the ultimate sandbox game? let us have total freedom from the start.
One thing I think they'll include is an updated 'ZIT' where you can find songs on the radio then download them to your phone and create custom playlists, also the phone should include the mission lists like in TBOGT.
I just cant wait to explore the place, I want plenty of hidden easter eggs, special/rare vehicles that don't spawn everywhere once you get one, plenty of radio stations, even more cars and vehicles, it would be nice to have the 'Top Fun' vans back too!
