Unless R* get innovative again with GTA 6, they will be left behind on next gen because there are other open-world crime games coming. One is code named: GTA Killer, just to give you an idea. If R* brings the same boring crap to the table again then they're done. Many other dev's are about to get some of that GTA-ish open world money. And these games won't be like Sants Row either. A lot better quality and physics. GTA & R* are in trouble in the future. But it's good for us. We won't be dependant on R* anymore and have to wait 6-8 years betyween games as we'll have "other options" --good options that will rival R*'s GTA in every way. I can't wait.
Can't wait til the day this happens. These Cockstar pricks still thinks they are the best in the world yet giving us a half-complete game like GTA V. Shame on them.
