I've got a nasty feeling that most of this extra time is being used to add a bunch of attention to detail to the world and I just hope they've been using the first 10-11 years to create actual new and interesting gameplay because I don't think people have been waiting 13 years to play GTA 5 with better graphics, more realistic water and beer bottles with nice looking bubbles in them.
If when this game comes out its STILL a Gears of War style cover shooter I'm gonna rip my hair out
