When Rockstar launched the 1.09 update for GTA 5 it arrived with patches and some extras. Players have enjoyed these but they have now turned their attention to wanting more.
Rockstar may have been listening to what fans want and if so the next 1.1 update could be awesome. Rockstar have already said that gamers can expect to see new heists.
Heists are what make GTA 5 stand out but at the moment they are available only in the single player game. Gamers have pointed out that the missions could be more realistic. Some gamers said that a feature in case plans went wrong could be included for more realism as gamers would have to think quickly and adapt. The forums over at Rockstar support is filled with what gamers would like to see and Rockstar could respond positively to them.
Casinos could make their way into GTA Online and gamers would have a chance of winning or losing money. Mini games could be introduced along the lines of poker and blackjack. This is something that has been seen already in Red Dead Redemption and files that have been recently leaked suggest that a casino DLC could be in the making.
Alien invasions were also suggested by gamers. It was said that perhaps aliens could appear from nowhere and gamers would have to stay on their toes to make sure that they were not abducted. This may not be too much of a stretch of the imagination as Trevor does have a close encounter. We know that Rockstar left many of their ideas unfinished so as to bring them in at a later date in the form of a DLC. Perhaps aliens are just one of things they had in mind.
Rockstar would easily be able to do any of the above and they did say that they were listening to what fans want.
