The Random Event System
Now, I'm sure most of us have played Red Dead Redemption over the past few days, one thing stands out to me, the Random Event System, which makes the world feel more alive by always having something happen near by where you are traveling. Now, I'm going over in my head at what parts could be used in the next GTA game and up to now here's a few ideas of how it could be used:
Pretty much same as RDR, you get called over to a broken down vehicle and a couple of gang members jump out the car and try and take you down, kill them to end the event and chose to spare or kill the vehicle owner.
Similar to RDR and Vice City's Good Citizen Bonus, low life criminals mug random people in the street, who shout out that they've been robbed, you chase after the criminal and either kill or knock them out in a fight, reclaim stolen items and take them back to the victim.
Since I doubt the next GTA game will have Coyotes and Wolves in the streets to attack people, replace these with thugs, who kidnap people and drag them off to alleys tobeat them, basic principle, take down all the gang members involved and make sure the innocent person walks away fine.
High Stakes Arm Wrestling
Duels are no longer a common thing, sadly, but as The Lost and Damned has shown, the Arm Wrestling Mini Game is both simple and quick to do, rather than have certain points to do this, you could have citizens in the streets who are sitting at tables, etc, challenge how tough you are and want to arm wrestle you, high stakes being that you could win $500+.
Point A to B Races
Very Similar to Burnout Paradise, at Traffic Lights you'll just get Drivers who want to have a quick race, from where you are, to a famous location in the city, kinda like the Taxi Fares, but more interesting.
Pretty much the same as RDR, but have these people on rooftops around the city instead, they challenge you and you get about One Minutes to shoot a certain numbers of birds out of the sky before they do. Simple.
There are just a few examples of how they could introduce that pretty awesome system into the next GTA game, because it does make a difference and really does make the land feel more alive, which is what GTA needs after the storyline is complete and 100% is attained.
