9. Gas/Petrol/Fuel Trail
As the second trailer displayed, the player, or possibly just Trevor, can make a trail of fuel from a canister and light it causing a range of destruction. A new feature not seen in a GTA before, this is something I am sure to be experimenting with as soon as I can. It is potentially a mission exclusive element of the game but fingers crossed it is available to Trevor, or Michael or Franklin, at all times. The potential to cause havoc are innumerable and this feature is sure to raise controversy with mothers, groups, and general anti-gamers, but when it comes down to it: a video game is an opportunity to do what you cant, or wouldnt do in real life.
8. Tennis
Tennis courts have appeared throughout GTA history and have been as useless as Claudes voice box, but as one of the early screenshots revealed at Michael's house they are yet again present and this time appear to be intractable. Again, like Trevors fuel line maybe this feature is exclusive to certain characters or more than likely not as the three protagonists can interact, and possibly verse each other in a game. Rockstar has experience in the area with Rockstar Games Presents Table Tennis so full tennis game with full tennis mechanics appears inevitable, also noting it had a cameo (inactive) in trailer two.
