2. Jetpack
I don't know about you, but I spent endless hours of fun in GTA San Andreas whizzing through the skies in a jetpack peppering below gang members with machine gun fire like a flying ninja. It was absurd, unrealistic, incongruous, and absolutely hilarious all at the same time. Also omitted from GTA IV and not to be seen in any GTA game since, we want the jetpack to return. Considering GTA V is once more putting a much bigger emphasis on flyable vehicles, it would make sense to bring the jetpack back, but part of me tells me it's just not going to happen now that Rockstar have started to take their GTA games a little bit more seriously. While it may have been passable in the cartoon-like PS2 era of GTA, where graphics weren't taken altogether too seriously, it's difficult to imagine it making a return in the more graphic-centric PS3 era. But we can hope, right?
