3. More Aerial Presence By The A.I
By "more aerial presence by the A.I" I mean I want there to be much more aerial activity in GTA: V. I don't want to be the only plane in the sky when I am tearing through the Los Santos airspace. In previous iterations of Grand Theft Auto I have been flying a plane only to look at the horizon ahead to see that I was all alone in the sky. Rockstar should put more A.I controlled planes up there to liven things up a bit. You wouldn't want to be driving down the highway and be the only car on the road, so why should it be any different with planes? We've all seen the above screen depicting the game's protagonist flying a fighter jet in close proximity to another plane (above) - again, this could just be a screenshot from a mission, but if this was replicated into the free-roaming aspect of the game then the skies would be a much more interesting place to be. Rockstar could even throw in mid-air collisions if they really wanted to live things up, or near misses etc.
Paragliding has been confirmed in GTA: V - wouldn't it be cool if random pedestrians had this function too? At the moment, exploring the sky is a lonely past time in Grand Theft Auto.
